The students in one of my classes asked me to support them monetarily so that they could compete in an inter-class football tournament. I accepted with the condition that they would let me be their team manager and coach. I love it when they call me coach.
Here are some of the things I had to avoid on the field the last time I played football:
patches of tall grass
goats crossing the field
the ball - it was waterlogged from the rain and weighed about five pounds
