I used to believe (up until about 3 minutes ago) that if you went for a wee in a swimming pool, special chlorine in the water would turn the water pink or green around you. The sad thing is the only reason I now know this not to be true is from reading other peoples beliefs from this site and coming across someone who believed the same thing as me. AND I AM TWENTY THREE YEARS OLD lol!!
A childhood belief about swimming pools
