I didn't go to improv class last week because I was sick. Today I went back. I was crabby as a barrel of Dungeness crabs during Crabfest.  I wanted to punch my most negative co-worker, Duane, for claiming that Olive Garden is a terrific Italian restaurant. 

Then I went to class, where it's just offer, receive, give; build and expand, listen with a different part of your brain, and everything feels better now. 

Magic. 

Here's a thing about improv and listening.
