Wish the lifeguard had the power to ask the parent and child to leave.

I’ve seen it before. It’s not pretty. The parent threatens (or actually does) call the cops. WTF people — it’s the neighborhood pool! The jump to aggression and the outraged entitlement that strips reasonable discussion out entirely gets me in a place I don’t yet have a name for. But it’s easy to see how we could get from “Son, don’t let anyone tell you what to do,” to “I do what I want.” (That’s how we get a swimmer from Stanford who lost his appetite (poor thing) because he raped a woman.)
