What a different world it was when I first sailed for Europe in 1930, with my mother, sister, and brother to spend six months abroad.

In the months leading up to World War II, there was a tendency among many Americans to talk absently about the trouble in Europe. Nothing that happened an ocean away seemed very threatening.

Belfast during the Troubles looked like a different world.

You can be involved in media, and you can be involved in all the handbag hurling that goes along with it, and it's a different world.

There are different kinds of people in the world.

With 'Delirium,' I had to spend time thinking about the political, social and religious structure of a different world. But it was a fun challenge.
