Silence is powerful.

It can make up everything.
Whenever I am down, I prefer silence.It gives me strength to come out of that situation.Whenever I get angry with someone, I prefer not to say a single word to that person.

I think, its the person who should search for the answer as to why I am angry with him/her.
Is it correct to do?Would one ever think as to what has gone wrong with the other person?Does these things matter to him/her?
