You're part of my body! I never had a problem with you before; you weren't fat, weird, big or small. You were great! You never gave me problems and I even admired the small scar you've been carrying around for 11 years.
Now, though...now you're being a total asshole. I can't bend you without hurting, I can't walk up stairs without feeling an ache, I can't do half the exercises I'm supposed to do because you decided that you don't want to work properly. What the hell?! I thought that doing exercises and losing weight was supposed to be GOOD for you! Instead, exercising has made you dumb. Really, really dumb.
Hey achy knee that has decided to crap out on me! YOU'RE A BIG JERK!
