At one point (right here) they discuss getting married. Tompkins said that even after living with his girlfriend for years getting married was an immediate change. They agreed that their relationship was a lot more powerful, and the word "wife" much mightier than "girlfriend".
Mulaney mentions that now he feels like he is looking after his queen. "Oh, that's my queen. I have to look after my queen."
"Wife is good. I like the word. Do you like saying the word 'wife'?"
Can I be forgiven for wondering why the heck people live together in the first place? I suppose as an arrangement for regular sex it has more dignity than hooking up, especially if you are thirty or forty years old. I don't think I'd have the emotional tools to pull it off, though. I'd either very quickly need to marry her or need to kill her.
Someone explain this to me. And don't say "practice" or "we have to make sure she's the one". I somehow think that's not how Tompkins or Mulaney would explain it.
