When I was little I saw an episode of The Golden Girls. In it the girls were throwing their friend a surprise birthday party, and he ended up having a heart attack and died. After watching that I believed that you could only die on your brithday. So every year the night before my birthday I would get really excited about the presents and party I would get. But then I'd get really sad because I thought I might die. I'd pray to God and ask him to spare me for another year. Needless to say I haven't watched an episode of The Golden Girls since then.
