Do you have powers

Personally i think i can read a person's mind. But i can only do so if i know the person well or we are very close. I know a lot of person and very often I've noticed that I can read their minds. I can even tell if the person is selfish or not. And sometimes can even feel whether they are lying or not. I'm a teenager and I'm not so sure of myself, so i keep quiet and never tells anybody anything. That's how i am.
