Why? Lessee. A conference table covered on coloring books, crayons, markers, pencils, a rubber chicken, rubber knife, dozens of Mardi gras bead strings, other toys. Walls with big posters of the periodic table of the metal bands, and the periodic table of curse words. A bunch of stuffies on shelves. A dozen or so plants on my window sills. Balloons. A ******, dripping brick on the corner of my desk. A magic wand hanging on the wall, that used to be a baseball bat in a previous life. Some foot high rude exclamation running round the top of the walls, that my staff would change weekly. Anything to make it festive. Outside my office, a countdown clock that counted randomly. It was offensive to some, until they realized it counted nothing. I used to change the message frequently. And an entire wall of Union notices, as I was the shop steward, as well as the evil management. Go figure.
I would never presume to judge anyone's decoration choices. I've learned to take joy in most everything.
No offense, just commentary.
