Nobody saves the letter that says “all good.” They save the one that says “I miss you.”

Being fine is easy to say and leaves nothing behind. What people keep are the messages where somebody admitted something: that they missed you, that they were struggling, that they were proud of you. Those get saved because they cost something to send.

Send one message this week that is more honest than your usual update. A single line about what you actually miss or actually feel is enough, and it does not need a reply to have been worth sending.
