Yeah and don’t forget that some people (although not necessarily a ton in the western world) don’t celebrate Christmas either. It was interesting to me because I met a young person the other day born in the US but to immigrant parents. Despite being born and raised in the US, he (and his family) don’t celebrate Christmas or anything.
In line with yours, I remember always being happy to work certain holidays like new years or memorial day or whatever because they aren’t holidays to me and I would get extra pay for being there.
