Waiting...Patiently
When the grandkids are coming over, we bustle about preparing for them. We sweep and vacuum. We pick up certain breakables and put them in safe places. We remove the basket of dog toys to another room. This must follow a very predictable pattern, because someone...someone...knows exactly what these activities mean. He goes to the door and stands there, watching and waiting...patiently...for them to arrive.
And when the do arrive? Happy barking ensues!
