I celebrated Christmas when I was growing up, so technically this isn't the first time. And last year I got a few Christmas lights and ornaments.
However, this is the first year in about 20 years that I had a proper Christmas tree. That thing is heavily decorated. I also have every room in my apartment decorated with garland, LED lights, and every sort of ornament and figurine. I have Christmas carols in my computer to listen to. In fact, my apartment has more Christmas lights showing from outside than most people's houses this year.
Unfortunately, I do not have any shopping list. Nor do I expect to get any gifts. But at least I want to have the place heavily decorated. It will be a slap in the Watchtower Society's face and that of the local congregation. It will also brazenly advertise that I am not one of those Je-Pedophile-hovah's Witlesses to anyone that might be passing by. And I had a heavy share in decorating the common area of my apartment sub-building. My hallway is the only one that has Christmas lights that can be seen from the main walk; my door also has a lit wreath that can be seen from the main sidewalk.
Sure beats donating to the Worldwide Pedophile Defense Fund.
