My buddy was helping me deliver papers when I was a kid. We switched bikes for a little bit, I gave him my mountain bike and I took his 10 speed. He warned me that out of the 4 options for the brakes, (2 on the drops and 2 up above), only 1 worked. The lever on the right drop, (rear brake). Well I was cruising along in a neighbordhood and came winging into a driveway. About 20 papers in one hand and the other on the brake. As I was approaching the garage I grabbed the rear brake, the wrong rear brake lever. I realized my mistake about a quarter of a second before I slammed into the garage. I swear you could hear the impact from 2 blocks over. Newspapers were everywhere. I quickly traded back the bikes. Luckily only my pride was hurt.
