I remember that me and some of my classmates were going from door to door selling lottery tickets.
I think we were supposed to earn money for a school trip.
And then we were outside my grandfather's house for some reason, counting the money or something and I was asking, in front of my classmates and my mother and grandmother: " How much is 25 X 4?"
and afterwards my mother was like "Goose, don't you know how much that is?"
And then I felt like a fool.
