My grandmother told me once that I couldn't eat watermelon when it was lightning because water "drew" lightning and it would strike me if I ate watermelon! I think this was just to deter me from eating at that particular time and she never told me any different. I believed this until I was a teenager! Be careful what you tell your kids!!!!!
