Stop flexing... Please!

Allen keeps standing his his doorway, flexing.

He stretches one arm by holding on to the top of the door fame and leaning as far forward as he can possibly muster. Then he stretches the other arm. Then both, so his whole body is jutting forwards.

All the while he is looking at me. I am looking away of course, making sure I don't catch his eye so he doesn't call me Kim - but it makes me feel sick, and I would really like him to stop!
