Here are a few "Don'ts" in Doubles (what NOT to do when playing).

1. Don't say, "I'm sorry," each time you miss. No apology is owed unless you denied a partner the opportunity to miss the same shot. Spare the drudgery - it's bad enough you ruined the point.
2. Don't remind your partner of the important next point. Most players immediately follow an insult with hitting the ball into the net.
3. When you miss an easy shot, don't say "Good Shot", "Good Serve" to your surprised opponent. Who do you think you are kidding?
4. Never demand an explanation. "Why didn't you lob?" It's just plain silly, because you may be wrong. Your partner may have been right, since a miss does not make his or her choice wrong. If your partner is stupid, why ask?
5. Be selective with yelling, "Yours." Yell when the ball is unreachable, then you can both laugh.
6. Use directions sparingly ("run up", "out", "stay" ). If the direction is not clear and correct, it is simply a nuisance.
7. Don't comment on every play. If compelled to analyze each point - go home and write a term paper or a book.
