Why do I even bother talking to people like that? They haven't affected me really... because I completely kept my temper, and honestly, two people like that telling me that I'm shallow, stupid, etc. -- the only thing I became was perplexed. I just can't comprehend how someone can be so blind to their own atrocities. Also I wasn't much affected because honestly, they attacked my strongest points. I am absolutely confident that I am both deep and intelligent (I may not be the quickest thinker, but I made a perfect 800 on the verbal part of the SAT, and generally learning has come easily for me), and people with that kind of attitude certainly aren't going to convince me otherwise, or even sway me.
Really, what could convince _your_cocaine that she is deep, while she justifies judging people based on how they look or their hobbies? It reminds me of nothing so much as paranoid schizophrenia; completely convinced of something that is absolutely not true.
