WHY are your going back there and giving that horrible instructor the satisfaction of a return visit. Hell, she wouldnt even show you the positions? The 105 degree temperature makes it a perfect place to be labeled as HELL!
This sounds like a punch line to a joke not a Yoga class...
I give you credit for your patience and ability to swallow your pride...
Personally, If I ever saw that instructor again, I would keep an eye on her/him in case he/she pulls a weapon.... Never know when the unstable types will go cRaZy...
