Oh trust me I bet a lot of your coworkers felt the same as you did but just didn't want to admit it. Most of my coworkers put on a fake act but there has been a couple who outright admitted their disgust when it had been just me and them away from others. I think people see me as very trustworthy and good at keeping secrets so I've experienced several people admitting stuff to me but they would never admit to anyone else since they knew there would be pushback.
This applies to all celebrations including birthdays as well since even birthday wishes and cards seem very forced to me and some coworkers don't even try to hide the fact that they don't give a crap. Also I agree that the whole thing of elves making toys never made sense to me too. Also living alone in the North Pole with elves sounds quite lonely and impossible to do. Also imagine all the stuff he would have to carry for just one trip around the globe lol. These are all the thoughts I had as a kid even though I kept my mouth shut and played along with it and you're welcome for making this thread.
