I don't know about anyone else, but I can't yawn intentionally. I could just be weird, though.

Anyway, I've yawned plenty of times at work, and my therapist has yawned too. I yawn when I'm dead tired.

Now, if my therapist yawned a lot, it would bother me. The yawning *itself* would not bother me, but if my therapist is always tired and therefore can't focus, then I'll be pissed because I'm wasting a $20 copay. I don't talk to dead squirrels.
