We've had a house-guest from Australia for the past week. He left yesterday, and as soon as we got back from dropping him off at the airport Bao curled up and went to sleep. A deep, determined sleep. He didn't even want to walk, this morning. He's exhausted. I'm exhausted. Christopher is a dear friend, but a week is a long time.

We went everywhere. We went out to lunch, and dinner. We went to Organpipe National Monument and Saguaro National Park. We went to Mexico. We went to the Tucson Museum of Art. We visited friends. We went shopping. We went to Festiva Encantada.

Bao has known Christopher since he was a tiny puppy, but even so, he sort of felt he had to keep an eye on things. He couldn't just curl up at my feet and go to sleep, because we were constantly on the go. And when we went places Christopher sat in the front seat of the car, where Bao usually sits. He wasn't enthusiastic about that, either.

I'm a morning person, and Christopher is a night owl. So every night he'd be prowling around at 2 AM, looking for stuff to eat. This didn't bother me (I'm used to Christopher) but Bao felt the situation needed monitoring. So the poor little guy is -- as Australians would say -- totally buggered.
