Dear Claire, I have a workplace situation that I’m not quite sure how to handle. I’m Jewish, and the guy in the cubicle next to me is Christian and VERY into Christmas. He decorated his desk with bright lights, put up a giant Christmas tree that partially blocks the entrance to my cube, and he plays Christmas music at top volume, all day long. He is also a big believer in the war on Christianity and complains about it every chance he gets. Now, I actually love Christmas, and I have no problem the decorations and enthusiasm, but the constant music, enormous tree, and frequent rants are beginning to affect my work. I don’t want to sour my relationship with the guy, as we work so close to one another and he is generally a great cube-mate outside of the holidays, so how do I ask him to tone it down nicely, without coming across as the angry non-believer?
