My boss "threatened" to decorate my cubicle for xmas over the weekend, since she and her daughter were coming in to do hers. I think she was surprised when I said OK. My reputation as a curmudgeon makes people assume I hate xmas, I guess.
Anyway, I was disappointed when I came in to see neither cubicle decorated. I was also completely unsurprised to see an email saying she was home with a sick kid today, because I pretty much assumed that would be the only reason they didn't decorate.
