Apologies and Volleyball

Whilst attempting to play a sport with my peers (why is there no solitaire of the sport world?) I found myself in the lovely situation of apologizing over and over again. As reflex. Confound you, etiquette. I don't mean to be annoying.

I've left my athletic shoes on in order to inspire me to exercise. Good luck, shoes. Ah well.

The other fifty percent of my time is spent running after the volleyball. Why does it have to be round?

I fail to see how it differs whether I fail while participating or when I fail without participating.
