A childhood belief about special powers

I used to have the notion that all people could hear what others are thinking, so I always was very careful about what I thought. After a few years of believing that, I came to the conclusion that only certain people could hear what others are thinking since I couldn't hear anybody's thoughts. However, because these people don't look any different from anybody else, I still had to be very careful about what I thought. I still think those certain people are out there, but I've managed to convince myself that they don't preoccupy themselves with my thoughts because there are other people whose thoughts are more interesting. ...once in awhile though, I still watch what I'm thinking, in case They are listening.
