When I was a kid and my mom took me to swimming lessons, I was so frightened that I threw up in the pool, and they had to get everyone out and clean the pool.
The next time we went, I told the teacher that I had to go to the bathroom, and then I got out and ran away. They had to chase me through the park where the pool was and capture me.
There are probably a lot of other reasons, but mainly those.
Although I would like it a lot if one of the Olympic athletes would throw up in the pool and then run away.
If any Olympic athletes are reading this, I will mail you five dollars if you do that.
Come on, it's just the Olympics.
