The last time I touched a skateboard I fell face flat onto the pavement.
All I was doing was sitting on it, going down the pavement, and when I brought it back up, I'd put my hands on it and push it up. On the way back up the skateboard hit a part of pavement that was sticking out, and I fell forward.
I was afraid to go outside until the wounds healed - the one time I did go outside, the next door neighbour's kids bullied me a little.
Luckily it was during Christmas holiday, so I didn't have to go school
