Usually they are.
I am scared of skateboarding ever since my friend fell off. He got a broken wrist, bloody face, bloody nose, huge face bruise, bloody knee.
His face was dripping with the stuff.
The weird thing was, he wasn't crying or anything, he didn't give any indication of pain. When I ran up to him and tried to help him walk faster, he growls, "Gerroff David I'll get along..."
The guy's a tank. Didn't even know that his wrist was broken until he got the x ray.
He goes on KMC but not too often anymore. Weird guy.
