I posted this on the Airedale list.
A few days of sunny, mild weather have made everyone lively and Alanis showed her stuff by doing playbows and tuckbuttruns at the same time as we chased around the yard this afternoon. I've read that people don't truly multi-task at work; they simply switch from one task to another very quickly so that they appear to have their attention on two things at once. I think you can DO more than one thing at the same time even if you don't think about what you're doing. Otherwise no one would be able to raise children.
But back to Alanis. I suspect she might have been switching from one move to another so quickly that she appeared to be doing both at once. She practiced this morning. Early in the day when it was just getting light, I watched her take a show stance at the edge of the patio, which looks down over the lower yard. One second she was facing east and the next second she was facing west, having whirled in an instant and stood again at attention. I'm naming that trick her Spy Move.
A person who knows more about this stuff suggested it's more of a Stealth Move. Others maintain that the laws of physics do not apply to Airedales and they can be in two places at once. Still another theory posits that Airedales are adept at magical illusions. I don't know which is correct.
