You sound like an empath. I guess if you can sense feelings as well, that would make sense. You just seem to be picking up on the contradictions between what is on the surface and what is underneath inside that person. Which makes sense because they are quite a contrast! The easiest way to cope with these thoughts is to recognize that they don't belong to you. And they don't have to be a bad thing either... you can have fun with them. It's a nice window into the way the rest of the world thinks.

I often strike up a conversation on the subject of someone's thoughts without realizing I have absorbed them.
