Who let the delivery men in? Who Who Who Who?

The delivery men had not arrived by the time I had to leave but when I got home I found the labradors had obviously let them come in. There had been a lot of running I think. They managed to make them stay inside the gate and there seems to have been no unhappy occurrences. When I asked the Labradors who had come there was much running in circles and a big play . No doubt there will be more exciting times tomorrow when the washing machine is actually delivered!!!!!
