Read a thing once about how thrift store and flea market sellers end up acting like accidental historians for regular people's lives. The stuff nobody wants anymore still holds all these memories and the sellers are the only ones left to pass them on. That dresser guy probably never told anyone that story before because who asks about a $40 piece of furniture. My mom sold a old kitchen table last year and spent forty minutes on the phone with the buyer talking about every scratch on it. I bet half the stuff on these sites comes with a whole life attached that never makes it into the listing. You got lucky that guy felt like talking.
