Track or No Track?

Today was pretty much average, minus the injury that finally showed itself today. I highly suspect that Coach Mlika is the one who put this sharp pain through my right knee from overtraining me (and the rest of the team) so early in the season. It was very painful indeed this afternoon, but after i iced it and took two advil, it's not so bad. Now that I feel better, my parents think I should go to the track meet, eventhough i already told the coach I cant go because of my knee. They're changing their minds!! I feel like I need to go to support my team, and if i can run, then run. I just don't want to be halfway through the 800 meter relay, and have my knee give out to pain. Also, now that the meet was postponed back to 2:00, i will most definitely miss the several social activities I had set forth for Friday night. I've tried to get ahold of Mlika many a time, but i cant get him. What should I do?
