The lesson that makes life easier

One lesson I learned several years ago is not to speak bad about someone even if it is the truth. I know just tended to let people do what they want and say nothing to anyone about it unless there a reason to do so. This piece of advice I found myself giving to someone recently. I sometimes have found that if something happening it’s best not to say nothing, to another person if they are not involved in it. I have noticed it can bring less hurt to a person too. Now I am not saying if there a problem I keep it to myself if someone does something to me I don;t like I am gonna let them know.
I have just learned not every one needs to know about arguments I might have with another.
