This woman was in my yoga class today

I take yoga at my local gym about three times a week and it usually is a nice and quiet place of zen, however it was brought crumbling down today. About three minutes before class..we got this lady in her mid-forties straggling in with sunglasses and a Red Bull. "What kind of class is this?" she exclaimed. I said yoga to which her reply was "what kind of yoga?" And before I could get a reply out..she loudly annouces to the class that "it was tough getting here by 11:30..did anyone else have a hangover...because I got a hangover." She plopped down her mat beside me and started making small talk which is just the most awkward thing. She was rattling off about her nagging shoulder when she takes off her socks..throws them behind her head and they promptly land on my new Air Max shoes that I bought from Dick's Sporting Goods. Then I began wondering if there has been any actual cases of violence during a yoga session..
