When my daughter turned 18, it reminded me of something simple but easy to forget: big birthdays are automatic milestones. They come with balloons, dinners, photos, and all the βyouβre grown now, woohooβ speeches. There are umpteen scripts for turning 13 through 25 β the OG markers of independence, responsibility, and new beginnings. But guess what: milestones donβt just belong to the kiddos. Sure, we still celebrate those over 30 birthdays with or without parties with 40-deep friends, or sheet cakes full of candles; but itβs a combo of βyeah, youβve made it another year and we love youβ β yet, unless we actively choose it, we donβt tie it…
