I saw this as an observer. The other day we did a community yard sale. Just a few families gathered together to offload random stuff as one does.
One family was selling some of their old video games for super cheap. A dollar a game or best offer. I don't know too much about games, but apparently they had two games of a trilogy.
Best paraphrase/recollection of the story I can do:
CB: Do you happen to have the third game?
Neighbor: No, we never bothered with it.
CB: So what am I supposed to do with these two?
Neighbor: Uh, they're a dollar each?
CB: Are you sure you don't have other game in your house? (Note: this particular neighbor wasn't even the hosting neighbor).
Neighbor: We never bought that one, man.
CB: Can you find it for me?
Neighbor: ...no.
CB: So you're saying these two games are worthless.
