If you say something like gunfire once, it can not be turned back. The scholars advised to talk only after hearing them understand. It is not always the answer to all the questions. You should learn how to talk like a good word and learn when you need to remain silent. Often your essential silence identifies your strong personality. In cases where you should be quiet:
If you do not know anything about it, it is good to keep quiet. It is a shame for you to argue unnecessarily.
It is a good thing to say no to the dear person, it is good to say no. There was a little silence on your lips!
When you understand that you are being considered unnecessary. You do not have to take your opinion. Then do not give up on your own. Rather try to understand the whole situation from silence.
The words can run out of people. Not to be forced to speak. So sometimes you can enjoy being silent.
It's good to protest, but judge the situation. If you see that you are being humiliated at some place, you do not have a situation to protest. Be silent. Keep in mind, the back of the war does not mean a rate. It can be time to sort out the strategy.
The mind is not good at all. Everything seems to be annoying. Keep quiet as long as you can. Because with good people you can use it for no reason. And for that you may have to burn in a fire of regret later.
