My hobbie and my downfall (2-21-12)

On Tuesdays and Thursdays I have a soccer class from 11:25am to 12:45pm and usually it's a pleasant hour and twenty minutes; Not today. Today we did some extra drills that we had never done before and the coach skipped group stretching in order to let us scrimmage since the drills were so time consuming. I thought we were going to stretch like in group like always so I didn't stretch on my own, big mistake. About 5 minutes into the scrimmage I suddenly felt a pinch on the upper part of my right hamstring as I jogged. As soon as I felt that pinch I wasn't able to jog anymore and I've been having this pain on my hamstring all day. So much for indoor soccer tonight, my friend wants me to go anyways to spectate, but for a guy like me who loves soccer, that's just torture. I'd rather just stay home.
