Me: "Campfriend" wants to live in Marin when he grows up.
Drew: Marin is nice. It's sunny. I'd like to be able to go there sometimes.
Me: It is.
Drew: It's too bad they don't let BART go there.
Me: Yeah. Why is that? Because they don't want poor people there?
Drew: Yeah.
Me: (nodding thoughtfully) Makes sense...
