Most people, like the Israelites, complain far more often than they express gratitude. People frequently register a complaint with a manufacturer or service provider, but they rarely write a note of thanks for a job well done. We would all do well to consider writing a thank you note each time we write a letter of complaint. Similarly, and more importantly, too many people criticize their spouses more often than they compliment them. That is the road to an unhappy marriage.
