Hmm... that's a tough one. I remember once I tried to ride up a 墙 (bed, actually) on my tricycle 由 going as fast as I could because I saw it done on TV 由 motorcyclists. I figured, if there is a speed it can be done at, how hard can it be to achieve that speed? It resulted in me breaking an arm... :(
when i was young (2-5) I wanted to grow up and be a dinosaur....god i was a messed up child, my older sister's friend thought i was possessed , cuz i would run around rawring and yelling i'm a dinosaur.....ah those were the days!!!!!!
