Go figure, you can miss what annoys you

It's funny how the people or things that annoy you are something you would miss if they weren't there. The same is true apparently for animals. Our neighbors got a new dog that my dog would angrily get in confrontations with daily, each fighting from their side of the fence. You would have thought she would be happy when they moved yet she seems to miss him. For a couple of days she would take off barking as she charged to the fence in attack mode. As time went on she realized the dog was not going to run to the fence to greet her. Now after she roams the yard she sits right next to the fence looking and hoping to see the annoying dog charging at her. Go figure.
