There are things that must happen at the same time everyday no matter what!! I MUST be up at precisely 4:30 am. Breakfast must be served by 4:40 am.
I know they always greet us at the door. They will be sitting in windows that face the driveway watching. When I'm on vacation I notice that about ten minutes before we normally come home they all start to yawn and stretch. They begin to gather in the kitchen when it's time for us to come home. Dinner is to be served within ten minutes of our arrival.
I say "Yes they have clocks"!!
