Improv class

So I wanted give my quick thinking a boost and joined a comedy Improv course. The first class was today and it was really cool seeing everyone think on thier feet, come up with something creative. It was cool to do random stuff like word association games, walking randomly and saying hi and bye to random people, emote like a duck, cat, ,owl, say funny sounding words and feel silly. There was a 3 step scenes game to be enacted between two people where 1 person says something and the 2nd person has to say yes reagardless, and the first person reacts to it and on and on. It was really fun seeing people coming up with random stories and making other go YES even when they strongly wanted to say NO.
It was the first time to perform in such a group and though acting these 3 scenes were difficult it was fun nevertheless.
