Glorious exchange with my mother tonight.
me: How much did you pay for the printing?
my mother: 19 pages, 3.80, so…38 cents per page.
me: WHAT?
my mother: No, what is it? Tell me!
me: [silence]
my mother: 4, no, 5 cents!
me: No! Who taught you math?
my mother: 2 cents.
me: [more silence]
my mother: 20 cents!
me: Yes.
