Today's Discoveries

I discovered two things today:

1. The booming voice lecturing in the classroom next to me belongs to one of the greatest philosophy professors of all time...I, a lowly TA, lecture next to a philosophy great.

2. When I was sixteen, I was the babysitter for one of my current students. Apparently we both look rather unlike we did ten years ago, because it's taken us three weeks to figure this out.
