<human>: Can you condense the text into three sentences or less?

This upcoming semester, my kindergarten children will be graduating and move onto elementary school. (We live in Taiwan, so naturally they aren't spending their time with family but at school). Since it would be my last Christmas seeing many of them, I thought I'd come to school for an hour and surprise them. When I told her this, she fucking flipped her lid. She told me that Christmas wasn't a part of their culture, although the school is covered in decorations and they're even having a Christmas party/gift exchange around the Christmas tree that day. She said that I'd see the the day before and after, and that they wouldn't even care to see me.

I don't think I've ever seen her this angry. She told me I was a terrible person. I know her favorite holiday is Christmas, but I've just spent a lot of time and money decorating our home despite myself hating the holiday. I understand being apart bothering her because I work until 7:30 every night, but I just gave up seven hours of teaching pay, which is quite a bit, so I could spend even more time at home with her. I just didn't expect this sort of reaction from her.

Am I being a twat? You tell me.
<bot>: My wife is angry because I want to spend an hour on Christmas Day surprising my kindergarten children, who will be at school.
