In first grade, I distinctively remember the teacher saying 'We're going to learn about odd and even numbers... 7 is odd' some kid near me asked -to anyone listening- why 7 was odd. I answered 'of course 7 is odd, look at it.' I had the idea of odd and even numbers, but I thought the odd ones were the weird looking ones.
