Festive flair

Today is the day I fulfill the official "new girl duty" of decorating the office Christmas tree. Having never so much as strung a light or held an ornament, I'm feeling a little apprehensive. What if I hang the angel or star (or whatever the thing is that goes on the top) in the wrong place? Is there a manual for this stuff?
Then I remembered the photos of a makeshift tree my dad put together when I was a baby, a salvaged, Duchampian readymade piece constructed from the bones of broken umbrellas found after a particularly intense New York storm. It was far from traditional, but there was no mistaking its identity. Why not make this a creative Christmas?
