RELATIONSHIP WITH PARENTS

1. Do your parents love you? Whether you believe they do or not, I have no intention of trying to persuade you one way or the other. Instead, I will tell you just when you find this out for yourselves. Actually not until you become parents yourselves. Then you will know.

2. Mark Twain, the great American writer, used to say when he was fourteen his father was so ignorant he could hardly stand to have him around. But when he was twenty-one he was astonished at how much his father had learned in those seven years.

3. Today, your parents may seem to you to be people who keep on saying: “Now when I was young..." But, believe me, that is how their parents seemed to be when they were young. Today parents are, in my opinion, more tolerant of the behaviour of their sons and daughters than ever before. I wonder, however, whether you are tolerant.

4. I heard recently of a father who was found sitting on the front steps of his house at three in the morning by a policeman. “What are you doing here?”, asked the policeman. “Oh,” said the man, “I've lost my key so I'm waiting for my children to come home and let me in.” But few parents stay our “partying” until the early hours of the morning. I wonder how you would feel if your parents started doing this and you had to wait up until they came in? Even if you didn't wait up for them! Would you not be asking such questions as “Where have you been? What have you been doing?” How would you react to their answers? What we all need, the young people and those who are older, is tolerance.

5. There are, you all know, black and white keys on a piano. Play them together thoughtlessly, without any rules, and you get discord. But if you understand music and spend some more time practising, you can, with the same black and white keys, produce sweet harmony. Why not try? You start. You'll be surprised at how quickly your people will respond.
