When I was little, my grandmother told me that my belly button is where all my skin was tied into a knot. I took her seriously and for almost a year I wouldn't touch my belly button, wash too close to my belly button in the bath, all in fear that if I touched it the "knot"/belly button would come undone, and all of my skin would fall off.
