The other day, I was cleaning out my closet, and I ran across a note a friend wrote me in high school. It detailed a school trip she’d been on. She and I have stayed in touch, and she’s now (among other things) a mother of two. I’ve thought seriously about returning it to her, so she can share it with her sons. In some ways, our notes were like a shared diary, and if I were her, I’d want to share that weekend with her kids, so they could see the unfiltered image of her becoming the person she grew up to be.
