(TWO THINGS STRIKE every Irish person when he comes to America, Irish friends tell me: the vastness of the country, and the seemingly endless desire of its people to talk about their personal problems. Two things strike an American when he comes to Ireland: how small it is, and how tight-lipped. An Irish person with a personal problem takes it into a hole with him, like a squirrel with a nut before winter. He tortures himself and sometimes his loved ones, too. What he doesn't do, if he has suffered some reversal, is vent about it to the outside world. The famous Irish gift of gab is a cover for all the things they aren't telling you.)
