I thought the first class was a good ice-breaker. Going up in groups in front of the rest of the class made it less awkward to be on stage. This class seems like it will be very interesting.
Last night i sat in convo and watched a group of girls eating dinner and talking. They were very animated and loud. They laughed with their entire body and gestured vigorously when they talked. I realized that i could identify the general topic of the conversation whether it was funny or serious by watching facial expressions and body language.
