sentimental: I was skipping rocks with my son the other day. That's something my grandfather used to do with me. It made me think back on the times I had with him.

I took my son to the lake the other day, and we ended up skipping rocks. I don't know why people skip rocks; it's not really fun or anything, but we did it. It reminded me of my grandfather and I when I was a kid, and we'd do the same thing.

Yeah, I hope so. You never really know what kind of moments someone is going to remember. I remember all sorts of things that weren't really important, but I guess they were important to me at the time.

i agree. i remember a lot of obscure things that my parents are surprised i remember.
