I remember first learning to ride my 2 wheeler bike. As I was small, Dad put blocks on the peddles. My elder brother would support me while I was wobbling nervously on the saddle. When he became distracted I would fall off! He would send the bike flying, shouting "peddle, peddle, peddle!", and I would fall off. My arms, legs and pride were bruised and wounded. But eventually I managed to ride it without wobbling, and I can still feel the sense of achievement!
