Well I have now tried my hand at wallyball, I have some new reasons why not to play
1. God gave all the wallyball genes in the family to Sam, so maybe he did not mean for me to play
2. I was completely terrified of the ball
3. I couldn't even see the ball half the time, let alone hit it
4. I now have very sore arms and wrists, that tingle a bit still from my attempts
Still, no one beat me up for being so terrible so it could have been worse.
