Oh Hops I hope all this has cleared up now, I must admit that what's in the water is what puts me off swimming. Public pools here are revolting, so much chlorine your eyes sting, bits of hair and old plasters, urgh! It makes me shudder. And friends who've worked as life guards and have all sorts of horror stories about people peeing, pooing and vomiting in the pool, honestly it has turned my hair grey. We have tidal pools not a million miles away but they're not covered by life guards and I'm not the strongest swimmer so I worry a bit about using them (definitely wouldn't do it with son, might venture in by myself but have a terribly irrational fear of freak waves sweeping in and carrying me out to sea). Anyway, I'm digressing, whatever the cause I hope it's getting better now. Have you heard any more about the monitor results yet? xx
