I don’t think it’s just “gift pressure”. But also social pressures from family dynamics and general “society expectations”.
I’ve seen people get downright evil at the supermarket over turkeys and hams, fretting over who is going to visit where and when, going nuts trying to coordinate everyone’s schedule so that everyone gets to visit everyone. (Whether they’re up to it or not.)
Junior needs a new suit and Jane needs a new dress because aunt Sally wants a formal dinner this year. What am I going to wear? And, oh, Person A wants to host dinner this year, and that offends Person B who thinks it’s a tradition to go to his house every year. Oh, and Person C is allergic to nuts, but Person D doesn’t want to change the family recipe that they’ve been using for generations, so Person C will just have to suck it up and bring an epi-pen. And Person E is a vegetarian and how the hell are we gonna accommodate that for Christmas dinner, I mean the nerve! And Person F’s baby is sick, but it would be appalling if they didn’t at least stop by, just for a half hour, it won’t kill them, right?
Seriously, I thought my co-worker would get divorced over some strife caused by her mother-in-law who absolutely insisted that they all had to spent Christmas DAY visiting her. Too bad for my my co-worker’s mom. Her family could have her visit on Christmas Eve or Boxing Day. Otherwise, the mother-in-law’s “Christmas would be just ruined! Why, if her son wasn’t coming Christmas Day, she may just as well kill herself.” Her son just had to be there for Christmas Day etc…, etc…
My family is very, very low key about it and always has been. We call each other and say “hello”, the who-hosts-dinner rotates so that no one person feels they must do it because they always do. So our family is happy enough with a very casual approach.
Not everyone is so lucky. A lot of people feel obligated to do things they aren’t necessarily prepared (or able) to do. Whether it’s the “gift pressure” or “social pressure”. It’s one thing to enjoy giving gifts and seeing loved ones, but it’s another when you feel burdened by unreasonable demands being made on your time, finances, or ability to accommodate visitors. Unfortunately some people have such high expectations of what the holiday “ought to be” that people feel held hostage by the season.
