Bad Manner : Speaking When Angry
Words, once uttered, cannot be retrieved. When angry, we tend to lash out at the perceived cause of our anger and we'll likely say hurtful things that we'll later regret. This is as true at work as at home. Again, an old adage, "count to ten before you speak," is especially appropriate when angry.
Regret and apology may help to contain the damage, but hurtful, insensitive, and inappropriate words have a life of their own. It's better to avoid speaking when angry, at least until you can think clearly and responsibly, and can consider how your words may be received.
SEVEN TIPS TO STEP INTO GOOD MANNERS:

• Don't interrupt.
• Don't finish the other person's sentences.
• Don't say "I knew that," or any other comment diminishing the speakers content.
• Don't use the words no, but, and however, as prefaces to launch your own conversation.
• Keep your eyes on the other person.
• Keep the dialogue going forward with questions showing you are hearing.

• Don't try to impress, it comes off as one-upmanship
