A couple of years ago we had lost power, it was in the summer time. So a bunch of us in the neighborhood sat in my neighbors, across the street, garage. Well they have a battery backup for their garage door opener and it beeps to let you know that it is on the battery backup. We were sitting there and the opener beeped. Tess did not like the constant beeping and she got up and walked across the street back home. She just layed on the lawn until I came home. It was a memory that I will always have.
