Several times a day, this is the view I have of Fitzroy:
That's to say, he's settled on the floor beneath a corner of my desk, and staring up at me while I work at my computer. From time to time, he gets tired of holding his head up, and he dozes for a quarter of an hour. When he's really bored, and wants to get out of the house, Fitzroy has developed an excellent technique aimed at letting me know that it's time to interrupt my use of the computer. As soon as I reach towards my mouse, Fitzroy simply raises his snout ever so slightly and bumps my wrist aside. When this happens, it becomes impossible to carry on using the computer, so I have to get up and bundle my dog down the stairs and out through the kitchen door.
Fitzroy has an even more eloquent way of letting me know that a break is necessary. He simply scrambles up onto my knees and places his head between me and the Macintosh. Clearly, there are limits to Fitzroy's patience with computing.
