have you ever been offended by a person who wasn't trying to be offensive by his or her language? in a way when the person is NOT trying to be offensive it makes the offense that much greater BECAUSE it means the words are more connected with his or her perception of the truth.
if you could follow that, you truly have a genius mind.
Anyways: You can't help but feeling like you have something to do with that perception or assumption or negation.... Its hard to describe--other than asking yourself, why. Why would this person think this capable of you or normal for you.
