My Boss = ASS

Okay - my boss is an Ass. Seriously an ASS. He is one of those big/muscle guys who is such a "guy." KWIM? Anyways, he has absolutely NO respect for yoga as an exercise, treats me like I am an 18 year old still in high school, talks down to me, and expects me to know all the machines, despite the fact, I told him I am here to learn that part of the job.
I am super sensitive, yes, but his attitude is seriously getting to me. I need to toughen up, I am determined to at least give this job the old "college try." It has not even been a week yet... most people hate the first couple weeks of a new job, right? HELP!
