Linguist-in-waiting: You are coming to that thing later?
Me: Only if I can find some money in my couch cushions. Or, if I win the lottery.
L-i-w: You won’t win the lottery.
Me: I could win the lottery!
L-i-w: You won’t win the lottery because you won’t play the lottery because you know how probability works.
Me: Huh. You’re not wrong.
