I don't really get the hate for real Christmas trees. Trees are a renewable resource, and the small ones used for this purpose aren't century-aged old growth. But hey, if you think it's more environmentally friendly to support an industry that manufactures fake trees out of fossil fuels, go for it.
When I was a kid my family used to drive out to a tree farm each year and cut down a real tree. These days my wife and I use one of those foot-tall plastic ones. It's less effort, easier to clean up after, and poses less fire risk. It does feel less festive but I can live with that.
Does "Grandma Cooked The Dog" count as a Christmas song?
