As a child, we celebrated Christmas on Christmas eve because my older sister's birthday is on the 25th. I always felt a bit bad for Maureen. People would give her one gift and tell her it was for both Christmas and her birthday. However, that was her problem. It only seemed weird to me.
The problem that I had with Christmas was that it seemed to be more stressful than happy for the adults. Also, the need to buy knickknacks for other people kept me from buying the slot car racetrack I wanted for myself. In return, I would get trinkets, toys, and clothes that cost everyone more than the racetrack that I wanted, if they had pooled their money.
