@revel,
Is it possible there's someone here who hasn't heard the real story of why some people put an angel on the top of the tree?
One Christmas Eve Santa Claus came back to his humble abode at the North Pole in a vile temper. "I've had it with Christmas," he stormed. "The weather's miserable out there, the reindeer were pains in the arse the whole trip. I'm all sooty from going down all those damned chimneys. I've had it. I don't want to see another decorated fir tree or a box with a ribbon on it for at least another year."
He sank down in his worn leather armchair in front of the hearth with a deep sigh, muttering under his breath.
"There, there," cooed Mrs. Claus and brought him a large eggnog, liberally laced with Cuban rum. He sipped it appreciatively and slowly began to relax. Of a sudden, there was a knock on the door.
Mrs. Claus, in the kitchen, said, "Would you get that, dear? I'm busy."
So un-jolly Old Saint Nick got to his feet with another deep sigh and trudged to the door.
Standing there, in the snow, was a little angel, dragging an already bedraggled Christmas tree. "Sorry to disturn you, St. Nick, and a very merry Christmas. But I've got this problem. An elf gave me this Christmas tree and I don't know what to do with it. What should I do with it."
So Santa told the angel what to do with it.
And that's why it's traditional to stick an angel on top of the tree.
