If you celebrate Christmas, you probably put up a tree. Year after year, you spend a pretty penny on buying a fresh one or you hurt your back lugging out the one in the box. You fiddle with the lights, place the ornaments just right, and struggle to get that star or angel straight on its perch. So why not show off this year's tree? Nothing wrong that you're proud of the way it looks — so go ahead, post a picture. After all, you can't invite all of us over for your holiday party.
