When my H came home for a funeral, I saw him looking at a couple photos of us that sit in my house. I didn't say a peep. Just watched him and let it go.
When I was with my H this weekend and we were talking, though, I found myself bringing up a few fond memories from our college days. Not about our R, but about a few experiences we had together. He laughed, but I kind of wish I'd only done it once, rather than once too many! Not sure I got to that saturation point, but I question things a lot and worry I overdid.
It's kind of the same thing you were thinking about when you were debating sending a photo, Uphill. Better not to go there, especially in an email which hangs around. Words fade over time, but emails are forever, and if they're irritating, that's a bad thing.
