Dear Theo,

Today you asked why the moon follows the car. We didn't have a good answer, so we're writing the question down for you instead…

Love, Mom and Dad

A letter, as they'll read it

Dear Mila, you won't remember today, so I'm writing it down. You wore your rain boots to the beach and refused to take them off…, even when they filled with water. You laughed so hard you sat down in the waves. I hope you're still that person: the one who keeps the boots on and laughs anyway.

— Mom

Written October 20, 2026 · Opens March 3, 2040, on Mila's 18th birthday
