I teach.

I teach swimming lessons.
I love teaching swimming lessons.
Sometimes I get sunburnt when I teach swimming lessons.
I always put put on sunscreen.
But sometimes the sun decides to evade my layer of UV protection and burn me anyway.
But I still love teaching swim lessons.
Small children are funny.
They are particularly funny when they think they know how to swim.
Usually they don't actually know how to swim. At all.
This is why I teach them.
I enjoy swimming long lengths on my back.
I also enjoy pretending to know how to do the butterfly.
Mostly I just enjoy teaching swimming lessons.
