This made me laugh. I used to sing in a huge choral group, about 86 people. We had to start practicing Xmas carols starting in the last week of August/first week of September. I'm one of those people that gets depressed and cranky at Christmas time. I hated to have to sing them for weeks, but if I wanted to keep singing with the chorale, I had to. This was a chorale with a wait list to get in, and you had to audition for a spot, so I was not giving up my place by skipping anything.
I will allow it the week before Xmas, and for the 12 days of Xmas.
