No Joy in Mudville.

I had a rough night last night with Mack. He weighed me and I had gained 1 lb. Then, he accused me of lying about what I was eating....which, of course...I wasn't. I've been eating his crappy diet the entire time. He kept insisting that I wasn't telling him something and I kept telling him that I had no idea what else I could tell him. That went on for a while (in front of the entire class) and then he gave me 1000 mountain climbers as a punishment. After I'd done about 115, he pulled me aside and told me that it was probably something I didn't know about....or [as I thought to myself] he's just a big asshole. Anyway, he let me join the rest of the class and told me to start again on my mountainclimbers next class and to round up the number I've done to 150. Thanks.... I'm really frustrated because I'm doing everything he says and not cheating at all. I don't know how much longer I can take this.
