As thoughts arise within your mind, they become energised, flowing out into the world in the words you speak or via your actions. When you think badly of others, then realise that your own thoughts can also injure you. So no matter what scenario you are in, or how aggrieved you are, you do not need to have the last word or symbolically win the argument. If you are upset, angry, or annoyed you may often find that your last words can often obliterate the wonderful intentions or the exceptional memories.
