It kind of annoys me when parents just drop their kids off and expect people to baby sit them even though it isn't their job. I'm not talking, teenagers, I'm talking kids, like 11,12,13 year olds.
Like at my subdivision where I live they have a large community pool. I know a lot of the lifegaurds there, and they say that parents drop their kids off there all the time, and expect the lifegaurds to "babysit".
