Open When Letters for Your Best Friend

Write open when letters for your best friend by choosing specific occasions, then building each message around a shared memory and something only you could say. Start with missing each other, needing a laugh, having a rough day, and celebrating good news. Use the labels and original examples below to make your own set.

Choose a small set you can finish

Try six letters plus an ‘open first’ note. Pick occasions that fit your friend’s life: a move, a demanding semester, a birthday, or an evening when you miss hanging out. Include happy occasions alongside comforting ones. Explain the gift in the first note: ‘Choose whichever letter fits your day. You can reread them, open more than one, or save them for later. No reply required.’ Choose labels from the table that bring a specific memory to mind.

Give every letter a different job

Jot down three things for each label: a memory, what you want your friend to hear, and an ending. For ‘you doubt yourself,’ recall something you watched them handle and name the quality you admired. Replace broad praise with details: ‘You stayed to help me clean up after everyone left’ says more than ‘You’re amazing.’ Read each draft aloud and replace anything you would never say in conversation. Keep your usual nicknames and expressions.

Open when you’re having a rough day: sample letter

Use this original example as a starting point, replacing the memory with your own: ‘Hey, you. I wish I could sit beside you for a while without making you explain everything. Remember when we missed the bus and spent the wait inventing terrible names for our imaginary band? I still think about how we made each other laugh that afternoon. You don’t have to turn today into a good story. I just wanted you to have a little company on the page. If you want to tell me what happened, send me a message and I’ll reply when I can. If you don’t, there’s nothing you need to send back. I’m glad you’re my friend, on the messy days too.’

Open when you miss me: sample letter

For a friend who is moving away, name what you miss without making them feel guilty for leaving. Try: ‘I miss the part of hanging out where neither of us had anything planned. Somehow getting a snack became an entire afternoon. I hope you’re finding places you like where you are, including a place with better fries than our usual spot. When we next catch up, tell me one tiny detail about your week. I want to picture your ordinary days, not just the big updates. And if we take a while to find a rhythm, I still want to hear from you. We have plenty left to talk about.’

Open when you need a laugh

Retell an inside joke, write a mock award for a harmless habit, or list wildly inaccurate predictions you once made together. A possible opener: ‘This letter officially recognizes your outstanding contribution to choosing the slowest checkout line in every store.’ Add the details that make the joke yours. Choose a memory your friend enjoys too. A funny photo with a good caption can stand in for a long letter.

Make room for pride and disagreements

For ‘open when you’re proud of yourself,’ leave space for an unknown success: ‘I want to hear the whole story, including the part you nearly left out because it felt like bragging.’ For ‘open after we argue,’ try: ‘I care about our friendship, and I want to understand what happened when we’re both ready to talk.’ Address existing disagreements directly before giving the gift. A sealed letter should not be the only place your friend finds an apology.

Put the letters together

Write the opening condition on each envelope and check that its letter matches. Consider adding a photo from the story, a doodle, or a handwritten recipe for your usual snack. Leave out other people’s private details and sensitive screenshots. Before sealing, check for promises you can realistically keep, especially claims that you will always answer immediately. Keep a copy if you would be sad to lose the wording.

Use Sealday for a letter with a known opening date

Sealday: Time Capsule Letter fits a birthday letter you plan to open together on the phone holding the capsule. Enter a Title and Message, optionally add a photo, video, or audio, then choose the opening date. Select Exact if you want the date visible before sealing. The writing screen is addressed to your future self; there is no friend or recipient selector. Sealday does not send the capsule to your friend or unlock it because they feel sad or miss you. Use envelopes for those occasions, so your friend can reach the right letter when they choose.

Keep a separate draft before sealing in the app

Save your letter elsewhere before pasting it into Sealday. Unsealed drafts can be lost when you leave the writing screen or when Premium access changes. The app can run paragraphs together when a letter is opened, so avoid wording that depends on layout. Keep original media separately: unreadable media can leave the memory screen loading. Wait for the sealed confirmation and check that the capsule appears on the home screen.
