Be aggressive, they said. Be tough. New York’s not like LA. You have to have balls in this city. So, I have managed a little over two weeks without much incident, give or take a suspected terrorist or two and a lost iPhone (spectacularly recovered from the local Jewish nursing home: never again will I speak out against the circumcision of infants, even though it is something I have come to admire in men over the years . . . But that’s a whole other story).
