After I watched Jaws for the first time when I was little I could not go swimming by myself. If I was swimming with family or friends and they got out of the pool I would sit on the steps in the shallow til someone else came in the pool. I used to think that Jaws would come out of the light in the deep end and eat me. I did this until I was about 16 and realized I was being childish.
