Worst: I was 7, I'm an only child and my parents were drunk. It was Christmas Eve and I asked if I could open one gift as was the tradition. I opened one, they were so preoccupied that I ended up opening all the presents by myself. They never knew the difference.
Best: When our first child was 11months old and it was a few days before Christmas. Putting up the tree, the lights etc. and watching her face was priceless. It really helps to have a good holiday when we turn out feelings and emotions outward rather than inward, concentrating on ourselves. We had the best Christmas because we were seeing it through her eyes and not letting it be colored by our own pasts.
