Just to chirp in--not against "normal" pool behavior at all. You're there to have fun, after all. But I hope all would agree that what I described goes WAY beyond acceptable. Those signs warning about running and diving are there for a good reason. And footballs are best left to the football field. And no matter who's doing it and no matter what a hoot it is to the families, throwing food in a pool where I'm swimming ain't nice!!!
