My sister used to torment me as all siblings do. Towards the age of 4 or 5, and she being 10..One way she did this was to chase me around the house with a screwdriver (not the real kind, just the lil tikes kind) and told me that if she put it in my belly button and start to twist it, I would fall apart. Needless to say, she won whatever fight we got in if she grabbed that screwdriver. Who wants to fall apart?!
