I have Googled, Binged, hit up Reddit and looked everywhere else I know to look and I simply can't find what I'm looking for :(
The story (I don't think it was a novella) is about a family reunion taking place (might be an engagement party, I can't remember). There's a kid there (preteen, maybe?) that nobody seems to know -- he sort of looks like both sides of the families that are represented at this gathering. Long story short, he's the son of a couple that is at the reunion. He came back in time to tape record them saying that when they had kids of their own, they'd never make their kid do homework, chores, etc. Really cute! I don't remember when I read it ... I want to say late 90's/early 2000's.
I'd be SO grateful for any help!
