I liked your description of your expression, dusa. I tend to daydream or play the "I'm going to sit on you game" with one of my dogs while I diffuse. It's boring.
Yes, I alternate sides and tilt my head. I don't dry everything all the way because I seem to lose body that way. And I try to remember to dry the back, too, but I sometimes forget.
One thing more is that I found I had an excessively hot dryer, and that it was melting the cheap bowl diffusers very quickly. (I've yet to find a high quality bowl diffuser, but I'm very much open to suggestions.) So keep yours on low or cool, if you can. Perhaps low/warm in the colder months and cool in the summer. If you feel like you're scalding your ear, it's too hot.
Dogs and nature abhor a vacuum.
