A childhood belief about around the house

I went to a friend’s spa party, and while I was in their spa I was suddenly busting for a pee. We were playing "spa evictions" so I couldn't be stuffed getting out. I decided to do my wee in there and kept playing. My friend’s mum came out to check on us and some one said generally "Oh I really need to pee" and my friends mum said "No one do it in my spa because this chemical reacts to urine and make a dark blue substance come out onto your pants.” A few people turned red, but not as red as me. When every one else was calling it quits I stayed in and I think people suspected. Eventually I came out of the spa and to my surprise nothing happened to my boardies! My friend told me later her mum always says that coz she hates people peeing in the spa. I never pee in a spa again as long as I live. And also a warning to you all: DON’T STICK YOUR HEAD UNDER THE WATER IN A SPA!
