I cannot figure out how he does it, but George knows before I do when the workers arrive.
Maybe he hears the truck, which is just a normal pickup not some big work truck.
What I find really funny is that as soon as he hears them, he bolts for the bedroom and hides under the bed or behind the drapes.
But how does he know it is them?
When the manfriend or my sister show up in their trucks, he doesn't run and hide.
When I show up in my car and even in the rental (which is now a truck not a Buick), he runs toward the door, not away from it.
But anytime a worker of any kind arrives, he bolts before they even make it to the front steps. He hates workmen of all types: cable guys, painters, plumbers, kitchen guys... whatever.
Maybe he has bionic ears.
