In my city, a very high skyscraper stands at the center. Somehow, a tree, in a span of [x] years integrates itself into the building. Its branches reach out from the top of the building and its shadow covers a big chunk of the city. At the time the story takes place, the tree's trunk is almost as big as the building itself.
It was such a sight, watching from a distance. But I figure it would be very inconvenient for those living under its shadow.
Why would my city allow such a tree to grow to such a magnitude in such a long time?
To clarify, the world is just like ours with the same kind of technology, except the tree, of course, where nobody understands how it works. The city was modelled after New York.
I imagine the people living under it may complain about the lack of sunlight. Maybe they want to hang laundry out to dry, but there's no direct sunlight. And then some couples may want a bit of romantic fun times under the moonlight on their rooftop. Stuff like that, besides, people complain about everything.
