Sounds simple, right?

This morning Zack got up first, and went straight to AJ's room.  He opened the door and announced "Hi AJ."

And we heard AJ say back, in his sleepy, first-thing-in-the-morning voice, "Hi Zack."

And even though we kind of wish Zack wouldn't wake AJ up, and even though it was 6:20 AM and Mark and I were pretty tired because we are both fighting off head colds, we looked at each other with huge grins.

Because that was the first time we've heard them greet each other like that.
