@MrsPramm - I try not to get caught up in that stuff too much. I might get a little bit resentful if, for example, my family decided to completely change our traditional menu for the holidays, but that's just because we never get to have Christmas ham and turkey any other time. Other than that, we make changes all the time. One year we did a secret santa, rather than trying to get gifts for everyone, because no one could afford huge amounts of gifts that year. One year my parents took a cruise on Christmas and the rest of us just had a casual meal and watched movies.
I think people can put too much emphasis on doing the same things every year, and this can lead to hurt feelings and disappointed expectations. I'm always hearing people talk about how Christmas and other holidays just don't seem the same anymore. But it really is just what you make out of it.
