haha im beggining to feel the same way. when i learn new techniques i get a sudden urge to try them out in a street fight. i never actually start a fight though, but one day some unlucky fella is going to feel the full effect of my training
wouldn't have thought you'd get a bruise from kicking someone in the thigh. its pretty much softer than most kick boxing bags, he must have had some boney legs or something.
