Why did they trim two trees for Christmas?

Neither Maniac or Grayson had decorated a Christmas tree in so long that they were overcome by the enjoyment..... thus, they got a bit carried away.

In fact, though they were delighted with their effort, the urge to trim was still full upon them. One room was simply too small to hold the spirit bursting. So they went outside and crossed the creek and tramped the woods until they came to a fine and proper evergreen, and there, their footsteps muffled by the carpet of pine needles, their every breath and whispered word arrayed in frosty white, they trimmed their second tree. This time the ornaments were nature's brilliant red-and-yellow necklaces of bitter- sweet, pungent pinecones, wine-red clusters of sumac berries, abandoned bird-bodied boats of milkweed, delicate thumb-size goblets of Queen Anne's lace.
