Hydrophobia.
Well, I'm claustrophobic in water which means that when I'm in a pool, id rather be along with respectuous people or, even better, alone with my boyfriend. Also, I hate to be splashed at a point that I'll turn agressive. And if you are one of those pool prankster, just don't think about dragging me underwater by surprise or you in for a fight... and I can be nasty when I'm mad.
