You will also never get the opportunity to replace words you have written in anger. Sleep on whatever words you wish to say before you say them, text them, email them. We should be measuring our words carefully because we may live to regret them.
Practice the art of talking to others. Be respectful and honest. Don't attack or get personal. Keep your "stuff" out of it as much as possible. Yelling and name calling is unkind. Ask questions, and above all, listen to the answers.
