person A: I took my son to the lake the other day_comma_ and we ended up skipping rocks. I don't know why people skip rocks; it's not really fun or anything_comma_ but we did it. It reminded me of my grandfather and I when I was a kid_comma_ and we'd do the same thing.
person B: haha..yeah it is kid of pointless but it is a little fun as a kid. im sure your son will remember 
person A: Yeah_comma_ 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_comma_ but I guess they were important to me at the time.
person B: i agree. i remember a lot of obscure things that my parents are surprised i remember.
