there are a lot of factors for me but i feel it, and i think a big part is climate change. i live in new england and it was 60 degreees and raining the other day, pretty hard to get into the holiday spirit when it’s spring outside.
Also, before the goblinos start, yes there are many places where christmas happens in summer, summer type weather, etc, but that is not how it was for me growing up and most of my adult life.
