I remember I told my parents something like: "teacher was laughing at me when I said I wanted to be an alcoholic when I grow up, why did she laugh?". I was about six, so they tried to explain why I should not want to be who I said I wanted to be. I think I understood more or less because I changed my mind and from this time on I wanted to be magician.

PS: I'm neither alcoholic nor magician today :D
