Know when people lie

I have recently been bothered with a lot of things around me lately. Now that i am mature enough, do we have any means to know if our friends are lying. I really hate people lying to me, I know that they have personal reasons for doing that but it doesn’t mean that it wont hurt.

Can anybody tell me at least three signs to know that a person is lying to us?

Isn’t it great to know when people lie to you? It’s been my dream to read people’s mind, coz through this we can retaliate immediately.. hahaha! Is there any science or study for that? well… peeps if you have more information on this.. kindly help me alrighty? thanks!
