My least favorite is Thanksgiving. There just haven't been a lot of good ones after I turned 12 and then my dad died 2 days after Thanksgiving 2014. I had to work a monster 12 hour black Friday shift in 2016. In 2019 and 2021 I just stayed back at home and in the hotel. 2020 was fine but I felt guilty going to my sisters because they were saying not to travel but I had quarantined and so had my sister for 2 weeks so everyone was telling me what we were was doing was different. I still felt guilty.
Christmas is my favorite holiday. Its changed drastically since I was a kid and even in the last 10 years but I still love it.
