We had Ramona's friend over yesterday, and this morning Ramona told me:
"C. said that I should use three squares of toilet paper."
Having been the one to personally help C. in the bathroom yesterday, I knew that she used four squares of toilet paper. She told me so after I'd flagrantly pulled off a number of squares too great to count.
"But I thought C. used four squares," I said to Ramona.
"Yes, but I'm only three. So I should use three."
"Oh," I said, the logic dawning. "That makes sense."
"Precisely," said Ramona.
