My T is really good about her phone. It has only "dinged" once during session for a text and she was really embarrassed about it.
Last session while I was talking I watched her stifle a yawn. She thought she was slick, but it actually looked like her head was going to explode. I wanted to say:
DAMMIT, JUST YAWN ALREADY!!!
It seriously wouldn't have offended me. I'd rather have her yawn at me than look like she's going to spontaneously combust!
