Don't talk bad.

Stop talking bad about others.

Do you want to know something about our friend?

Wait a minute, Before you start telling, i would like to give you a test.

There simple questions, if you pass them, then i'll be glad to hear those news,

First: The news you want to talk about, are you sure that it is the true?

I dont know, i just heard it from a friend.

Good, you don't know if it's true or not, but still you want to talk about it. Ok, let's get to the second question. The news you want to talk about, is it a good part of him or a bad part of him?

It's his bad part.

So, you want to tell me something bad about your friend which you don't know if it's true or not? The last question is,

The news you are about to tell, will it be useful for me?

No, not really.

So, the news you want to talk about is neither true, nor good nor useful, so why do you insist on telling me so?

-Socrates-

It's fun right just to hear bad stuffs from our friend? haha.
