There is a large tree about one block from my office that I never noticed before late this past summer. It was on this occasion that I noticed that there was a certain stench coming from the area that I realized that something was not right. Living in New York, I am not immune to noticing certain unpleasant odors from time to time but my first thought was, "Someone had a wild night last night." Assuming that someone had thrown up in a nearby garbage can.
The stench continued day after day until I eliminated the possibility of someone throwing up in the same garbage can every day for a week.
Then I noticed that the tree had been dropping some seed-like balls and the more that were squashed on the ground, the more it smelled. The tree was the culprit.
So yeah, this was a long time ago that I realized that the tree should hence be called the Vomit Tree, but now that it's fall in New York, the leaves are turning a lovely golden (non-vomitlike) color, I have a new appreciation for it.
