not cool at all.your parents def. need to put a stop to it and soon. there's way too much liability involved with a small child. sounds like your parents need to lock the gate and tell them to call next time. what if y'all just shocked the pool and it was full of chlorine or you had friends coming over? i just don't understand the nerve of some people. sure, i've had people tell me "stop by anytime" but i don't take it to mean stop by whenever i feel like it without calling, that's so rude. we have a pool and there's no way in hell i'd ever allow someone to use it if we weren't home. i don't even let my teens get into it if we aren't home, way too scary.
