Indeed once Christmas is over many throw the once wanted tree outside and it's good to hear you used that fact to write this this story. I am super happy this tree has a second life.
In Dutch we sing: Oh pine tree, oh pine tree (the translation of the German: Oh Tannenbaum, oh, Tannenbaum) but most of us have a spruce tree instead. The white version is way more expensive.
I get so annoyed with everyone throwing their trees into the street that I thought that at least in fiction, I would come up with a better solution!
