Like it says on the box.

Scene: Steve and Jane have met me at the bus stop after work, and we are walking home in the dark. A tall guy with DJ headphones around his neck is standing on the corner across the street from us, right in front of our house.  

As we wait for the light to change, he dreamily does tai chi.

We cross. 

Me: "Hi."

Him: "Hi." Pause. "Very high."

I bet you are, buddy!
