BARBARA: Second best just made full professor at MIT. All I’ve made are beds.
RUSTY: How was your day.
BARBARA: Well, I figured out today that it’s ten years this week that I’m working on this dissertation. I thought we’d celebrate. Going to take us to dinner?
RUSTY: All right.
Son: Why don’t you just give up on that dissertation? It makes you miserable.
RUSTY: Your mom’s not a giver-upper.
BARBARA: Maybe that’s BARBARA problem.
Son: I sure wouldn’t do math if I didn’t have to.
RUSTY: I’m afraid you got my genes in the math department. If it wasn’t for your mom I’d still be taking algebra.
BARBARA: I had to be good at something.
RUSTY: You were good at everything.
