Okay, I have a gift of knowing but there's just one problem... I can read most people but I always for some reason come in contact with people I can't read even of that person is my friend I can't read them I can read all of my friends just not a few? Why is that? How come I can read most but not all? What's keeping or blocking me from reading that person?

What do you mean "read people"

I can read people meaning I can tell a lot about the person and basically know them everything about ten before I even meet them but there are some people rant I know and are friends with but for some reason I can't read them

I would say it's an age thing, as you mature you'll understand better. Good luck

Not all is meant to be known. Some people aren't who they try to portray themselves as. As far as people close to you even psychics will tell you Its harder because you have the emotional bonds that cloud you.
