Eating Pavement

So today on my bike ride home from school I totally wiped out.  I was riding on the side of the street (where bikes are supposed to ride).  Whenever I get to an intersection where the light is red I like to get on the sidewalk so I don't make people mad who want to turn right.  I was on my way to turn up on the sidewalk where the curb dips down at someone's driveway.  But there was a lip on the driveway entrance and the pavement was wet from someone's sprinklers.  All of these circumstances led to me wiping out, scraping up my elbow and knees and getting bruises on my shins from the pedals.  Not cool man, not cool.  I'd like to blame it on the fact that my bike doesn't have hand brakes, it has back pedal brakes.  I didn't know this when my mom bought it for me, so when it arrived I was a little saddened and now I know why.  Pictures to come.  Meh.
