To make others less happy is a crime. To make ourselves unhappy is where all crime starts. We must try to contribute joy to the world. That is true no matter what our problems, our health, our circumstances. We must try. I didn't always know this, and am happy I lived long enough to find it out.
Lebanon was at one time known as a nation that rose above sectarian hatred; Beirut was known as the Paris of the Middle East. All of that was blown apart by senseless religious wars, financed and exploited in part by those who sought power and wealth. If women had been in charge, would they have been more sensible? It's a theory.
Parents and schools should place great emphasis on the idea that it is all right to be different. Racism and all the other 'isms' grow from primitive tribalism, the instinctive hostility against those of another tribe, race, religion, nationality, class or whatever. You are a lucky child if your parents taught you to accept diversity.
There is a part of me that will forever want to be walking under autumn leaves, carrying a briefcase containing the works of Shakespeare and Yeats and a portable chess set. I will pass an old tree under which once on a summer night I lay on the grass with a fragrant young woman and we quoted e.e. cummings back and forth.
