Letter to Your Best Friend: 3 Examples and Prompts

What to put in a letter to your best friend

Choose one reason for writing today. You might want to tell them something you usually hide behind a joke, remember a shared afternoon, or pick up a conversation that has gone quiet. You do not need to explain your entire friendship in one letter.

Before drafting, write down three details only this friend would recognize: a place, a phrase, and a small thing they do. Those details give you something better to work with than a list of qualities like kind, funny, and loyal.

• A familiar greeting: use their name or a nickname they enjoy.
• Your reason for writing: tell them why you wanted to give this thought more space than a text.
• One shared scene: include what happened and the detail you still remember.
• What it means now: explain what you appreciate, miss, or want them to know.
• A natural ending: share a small update, an invitation, or a warm closing without requiring a reply.

If a sentence could be sent to any friend with only the name changed, add a detail that belongs to the two of you.

Example 1: a short, casual letter to a best friend

Use this version when you want to say something kind without making it a formal occasion. The humor should sound like a joke you already share.

Hey Rowan,

I found the receipt from our attempt to cook dinner last Friday. Four ingredients, two emergency trips to the shop, and somehow we still ordered noodles. I am keeping it as evidence that our confidence is much stronger than our cooking.

I liked that evening. We had no exciting news and no good plan, but sitting on the kitchen floor with you made the week feel less rushed. I wanted to say that before the memory turned into just another photo on my phone.

Next time, I vote we order first and pretend it was the plan all along. Send me your most unreasonable menu suggestion when you have a minute.

Your fellow terrible chef,

Ellis

Example 2: a heartfelt letter to my best friend

This example is for the writer who has something sincere to say and usually changes the subject before saying it. Notice how a particular memory carries the message.

Dear Maya,

There is a part of our train journey last month that I keep thinking about. I had spent the whole weekend being cheerful about the move. Then we sat down, you handed me the window seat, and I finally admitted I was scared.

You did not rush to tell me the new job would be wonderful. You asked which part worried me most. We talked until we nearly missed our stop, and for the first time I felt able to describe what I was leaving as well as what I was looking forward to.

That is something I value about you. I can arrive with a mixed-up answer and you still want to hear it. You also tell me when I am being unfair, which I appreciate a little later than I probably should.

I hope I give you room to be that honest with me, too. You do not have to be the person with the sensible answer every time we meet. I want the unfinished version of your news as much as the good version.

I am settling in here. The kettle leaks, the road outside is louder than expected, and I still turn to tell you things before remembering you are not in the next room. I will save a few stories for our next call.

With love,

Nora

Example 3: a letter to reconnect with a best friend

Use this when everyday life has interrupted contact and you want to reach out. If you caused a specific hurt, address it directly rather than asking a friendly note to do the work of an apology.

Hi Sam,

The book you lent me is still beside my bed. I finally reached the chapter you told me about, and I wanted to argue with you about the ending immediately. It made me realize how long it has been since we had one of our completely unnecessary debates.

The past few months have been busy here, and I have let too many weeks pass between messages. I miss hearing the everyday things: what you are making, which colleague is testing your patience, whether the balcony plants survived.

There is no big announcement behind this letter. I wanted to say hello properly and make room for us to catch up. If you would like to, we could have a short call one evening next week. If this is a crowded month for you, we can find another time.

I hope you are doing well. I am returning the book only after you explain that last page.

Take care,

Alex

These examples are fictional. Borrow the shape, then replace the names, memories, invitations, and wording with details that are true for your friendship.

Letter prompts for your best friend

Answer two or three prompts in rough sentences. Keep the answer that brings a real scene to mind, and build around it instead of trying to include every topic.

• Which ordinary day with them would you happily repeat? What made it good?
• What do they remember about you that most people overlook?
• When did you disagree and still feel understood?
• Which shared joke has a story you have never written down?
• What is happening in your life that you would tell them if they were beside you?
• What do you enjoy about them beyond what they do for you?
• What small plan would you like to make together?
• What have you been meaning to say without expecting anything back?

Make the example sound like you

Read your draft aloud once. If a line sounds like something you would never say, simplify it. A friend who knows your voice will recognize a plain sentence faster than an elaborate one borrowed from a template.

Keep jokes your friend enjoys and leave out stories they would find embarrassing. Be especially careful with private information about other people. A letter can be meaningful without recording everything you know.

An opening such as “I wanted to tell you this properly” works when you feel shy. “I saw this and thought of you” works for a lighter note. End with the closing you normally use with them. For more options, see how to start a letter and how to end a letter.

If the whole message is about one favor, the thank you letter guide gives that purpose more attention. If you need to take responsibility for something, use the apology letter guide before choosing an example here.

Share an online letter with your friend

You can put the finished words in a handwritten note, a message, or an online letter. Choose the format your friend will actually be comfortable receiving. A digital letter is useful when you want a separate page they can bookmark and revisit.

With Secret Letter, open the composer, enter your message, choose a future reveal date and time, and create the link. For a message you want them to read soon, choose a convenient time close to when you plan to share it. Send the URL yourself through your usual private conversation and tell them when it will open.

The service is free and requires no account. It does not deliver the letter automatically or send a reminder, so keep the URL and a separate copy of your words. Access is private-by-link: anyone who obtains the URL may be able to read the message after the reveal time.

If your goal is to preserve the friendship for a later milestone, use the letter to a friend in the future guide. It focuses on what to record now for a reader meeting the words months or years later.
