"Sometime over the course of a person’s first year in New York, there usually comes that moment. It can happen in the first days or weeks, or after 10 months. It can happen repeatedly, or without people noticing, at least not at first.
Newcomers suddenly realize either that the city is not working for them or that they are inexorably becoming part of it, or both. They find themselves walking and talking faster.
The subway begins to make sense. Patience is whittled away; sarcasm often ensues. New friends are made, routines established, and city life begins to feel like second nature. In other words, newcomers find themselves becoming New Yorkers."
