The one hard and fast rule in my house for Christmas morning was that you could not wake up Mom and Dad. They didn't care how early we got up, but we had to wait for them to get themselves up and ready before we could open presents. The wait was always excruciating. "Santa" usually left out one of our bigger gifts all assembled and ready to play with. Plus we got a special treat in our stockings: mini boxes of sugar cereal. The only day of the year when Fruit Loops and chocolate coins were an acceptable breakfast. When it was time to open presents, we would go around in a circle and take turns. I like doing that because it prolongs the process and you can watch what everyone else got. How do you do presents in your house?
I just remembered that there was a year when I was in college that my parents managed to get up and dressed before any of the rest of us did. You know everyone is getting older when the parents actually have to drag the kids out of bed to open presents!
