When I turned 8, I made a wish as I blew out my candles. That wish came true on July 5. I had wished for a little brother. I was very, very pleased with my birthday-candle-blowing-wish powers.
It took several years for me to figure out I wasn't really responsible. That maybe my Mom and Dad had something to do with it. Especially once you realize that The Boss Man was born 3 months after that birthday. :)
