They deserve a big thank-you for that. You don't have to like your parents. But it feels better if you learn to love them. My mother had a great deal of trouble with me, but I think she enjoyed it. If you really want to hear about it, the first thing you'll probably want to know is where I was born, and what my lousy childhood was like, and how my parents were occupied and all before they had me, and all that David Copperfield kind of crap, but I don't feel like going into it.
Laughter is inner jogging.
If it raised the cholesterol count or had too many calories, people might do it more often. If laughter were only forbidden , then people would do it all the time. We'd have laugh police. If they caught you laughing, they'd write you a ticket. Children's TV programming would have to be monitored very carefully.
