When EG has students coming and going in the house, we try to rotate which dogs are outside, having one tied out while the other two are indoors and/or crated. This is not because our dogs are mean; they love people so desperately that they will jump on them, jump on their cars, and even try to get in through the open windows.
Tonight I tired of Penny's yapping and finally tied her out, telling the girls to hold Dirty Harry, as he will barge out with whomever is going. The girls tied Harry to the basement doorknob. When I came back in, and went to untie Harry, I had to push him backwards, quite forcefully, to get the leash loose.
I wondered if this was a metaphor for life--do we sometimes need to go backwards in order to go forwards?
