"Like wrestling a martian"

Not too long ago a guy tried to cut in front of me in line for the bar at a fancy rooftop party. After a verbal exchange I squared up with him without even thinking. Actually, I was thinking Really?!? Do you know what you're getting into? Fortunately he backed down. It would have been extremely stupid to get in a fight over almost nothing. But those old instincts die hard.

The friend standing next to me (another scientist!) was amazed by the whole thing. I guess I was too.

Mama said knock you out.
