One of the things that is particularly strange for someone who grew up in Texas (such as myself) to adjust to upon moving to America's Favorite Borough is the climate. I had expected it to be a bit cooler here, since it is further north, and a bit more damp, since it is on the ocean. There are hot spells, sure, just like there are cold snaps back where I am from, and some dry days, but for the most part, things are as expected in that regard.
The problem is the amount of sunlight.
I had not expected what I have gotten for the three autumns I have lived in New York thus far, that night would begin to fall at four in the afternoon, or that before seven in the evening, it would be dark. I understand why it happens, of course (axial tilt...the same thing that is the actual reason for each season), but it is damned screwy to have to live through it, especially when I grew up use to the strong but kindly Hill Country sun.
Then again, I spend most of my time inside. It really ought not to matter.
