There is a man w/ a silly pointy beard and his tubby, upper-teenage son, that throw a ball across the pool everytime they are there. Before I had a child I didn't mind it. I enjoyed watching them dive 5-7 feet to their left or right to catch an errant throw. But now that I have a small one playing in the pool I feel as if the boy and father don't observe other swimmers as well as I, a concerned parent, wish they would. My child has now been hit by their ball no less than 10 times (only made my child cry 2x, but that is 2x too many). Additionally, the once fun-looking diving to their left or right 5-7 feet for errant throws has resulted in my child being landed upon 1x by the tubby boy.
I realize how prudish this comes across, but I'm only a concerned parent.

lifeguard's reaponsibility

I think this is why we hire lifeguards to monitor the safety of everyone in the pool, drowning or not. They aren't there just to get a tan and earn some easy cash.
