Rob started some Celtic Christmas music playing on the stereo. It starts with the sound of geese honking as they fly overhead. Brodie ran to the window to look for them. Bradley stood in the room looking around. Rob thinks that is so funny. And it is. So now when they are playing hard, he'll start that song and watch them both stop and listen. Brodie doesn't run to the window anymore and now Bradley looks at the speakers. They seem to know that no matter what is going on, that sound means to pay attention.
