Today gave an indication of Abe’s cleverness. We live along a busy highway (by country standards), with lots of oilfield traffic. This afternoon, Abe was outside and barked to let me know that someone was here. I stepped to the window to see the UPS truck coming down the highway with the turning signal on, just starting to slow down to turn into our driveway. The UPS truck wasn’t to the driveway yet, but Abe knew he was coming here. Was it because of the turning signal? That’s my bet.
Oilfield pickup trucks often park at our turnout so occupants can talk on cell phones, and Abe never bothers to let me know about them. The UPS truck comes here often, and never gets barked at unless he’s coming here - not when he's just driving by on the highway. The truck is quiet, so it’s not as though there is any major noise warning.
Regardless, Abe knows that I want to be alerted when UPS is arriving, and not alerted when the oilfield workers are using the turnout. He’s a very good boy, our honest, clever Abe.
