You know you have lived in New York too long when you step over a one-legged woman on heroin who has fallen out of her wheelchair at the corner of 14th Street and Second Avenue. You have lived in New York too long if you don't even think about helping because you don't have time to care and that you really can't care anyway, because what are you going to do? You have certainly been here too long if you think, she's fine.
I think in most other places, still, a person collapsed on the street = get help.
Maybe not LA. Maybe not San Francisco.
You have also lived in New York too long if you own a vehicle with a sign in the window that tells all who may be even remotely interested that there is "No Radio - Anymore."
