Zack is growing up. He’s 3 now so he has slowed down a little. He’ll jump for joy when you arrive and escort you to your room and make sure everything is ok there. Then he knows not to come up and bother you. He’ll be overjoyed to see you in the morning for breakfast and most likely herd the table, run circles around it, so that you don’t go away again. You don’t have to worry, he’ll be right there when you leave also. Part of his job is to say good-bye and run the fence line and protect the house. He is exuberant and loves people, but if he is too much for you just say something and I’ll calm him down.
