A Letter to a Friend, to Open Together Years From Now
Adult friendships rarely end — they just quietly fade. No fight, no goodbye. You graduate to different cities, someone gets married, and the chat thread sinks to the bottom of the list. But there's always that one friend you refuse to let drift away like that. A letter to the future is a clumsy, earnest way of holding on: write down the stupid things you did together, the dreams you swore you'd chase, the thank-you you never said — and send it to their birthday five years from now, or to a date the two of you pick. When it arrives, whether or not you still talk every week, they'll be holding proof that someone once took this friendship seriously. Many friends write in pairs: swap emails at the farewell dinner, each write one, and agree to open them on the same day — a time capsule you bury together and dig up together. Below are letters to friends that writers chose to share. Write yours while you still remember the details.
Ideas to get you started
- Put in the things only the two of you understand: the joke you've retold a hundred times, the trouble you got into together. Those code words will make them laugh out loud on opening day.
- Say a real thank-you — friends almost never do. Name the exact moment they pulled you through.
- Make your predictions for five years out: same city? Who gets married first? Check your answers when you open it.
- Get them to write one back. Same delivery date, opened together.

你好,中秋节快乐,真的很谢谢你喜欢我,让我知道我也是会被爱的那方,但是我从不认为把朋友变作恋人是一种好方法,我不希望短暂的甜蜜毁了我们长久的友谊,或许是在爱情这方面对你有很多吸引,但在友谊方面你更是我不可多得的挚友,所以我现在在默默看着你,直到你真正找了一个可以陪伴一生的人,我才会放心。现在我找到了

见字如晤展信舒颜不知道你能不能准时看到这封信,但当你收到这封信的时候,也意味着我们的初中已经毕业一年了。我先讲一下我为什么打算写这个信吧,首先就是受到电影《给阿嬷的情书》的影响还有就是忽然收到了去年写给自己的信,然后就有感而发。不知不觉我们已经上了将近一年的高中生活。以前呢,总感觉过得很慢很慢,可是

离别信
亲爱的诗语见字如晤,展信佳。 想到我即将要踏上一段新的征程,我其实内心不知是何种滋味。我想,我无法轻飘飘地说出那句“再见”,因为离别于我而言,是个沉重的字眼。 有朋自远方来,又赴远方。我们一起经历了那么多美好的时刻,一起分享喜悦与悲伤,这些都将成为我回忆里的珍藏品。 人生中有太多个分岔路口,我们要在

Frequently Asked Questions
How does the letter reach my friend?
Just add their email or phone number when you write. On delivery day they'll get an email and a text, and can open the letter via the link or its 6-digit claim code.
What if they change their number or email by then?
The claim code is the safety net — give it to them now, or hold onto it yourself; it works no matter what changes. You can also send the letter to your own inbox and forward it personally when the day comes.
Should I tell them I wrote it?
Both ways work. Keeping it secret until delivery day makes it a surprise; agreeing to write for each other and open together makes it a ritual. Farewell dinners and birthdays are perfect moments to make the pact.
