Marriage means commitment. Of course, so does insanity. A metaphor is like a simile. Minds are like parachutes - they only function when open. Misers make wonderful ancestors.
Mistakes are often the stepping stones to utter failure.
The more sins you confess, the more books you will sell. The most effective answer to an insult is silence. Never ascribe to malice that which can adequately be explained by stupidity. Never call a man a fool. Borrow from him.
