my mom cured me as follows:
7-year-old me: "mama look at my toe-- it's peeling. what is WRONG WITH ME?!?!"
mama: "oh? look at that! that's what happens three days before you die!"
me: (ran off screaming and crying... probably wrote a will--- i was obsessed with writing wills at that age)
after years and years of this i finally figured out xyz wasn't going to kill me.
