A childhood belief about bathrooms

I used to believe there were shower monsters that lived in the shower but hid when there was water in the shower or bathtub they hid down the drain because they were alergic to water. My sister told me that i was lucky they hadn't killed me yet. I asked her why and she said because you don't sing when you go to the bathroom. So from then on I sang while going to the bathroom to keep the monsters having too much fun dancing to my music to eat me. Then whenever I went to someones house and had to use the bathrom I would ask them how many monsters were in their showers so i would know how loud I had to sing.
