Pride

This is going to sound egotistical and dogmatic, but I really must say that sarcasm in some sense is a form of art that requires, at least, some halfway intelligent thought. The greatest of sarcasm requires good wit and quickness right along with excellent delivery.
I know this girl who rants and raves about how sarcastic she is; she thinks it's all outrageously hilarious as well, but she makes me clench my teeth every time she attempts sarcasm because it's absolutely obnoxious and completely devoid of any tact. There's no thought and it's the most obvious, expected bit of words.
Maybe my ideas of sarcasm's purpose aren't what everyone else thinks they are. Personally, I love to be surprised and amused even if it is, unfortunately at the time, at the expense of someone else. I can laugh at myself, and in my perfect world everyone else would be able to do the same with such thick skin as mine. It's not the case though.
I've always thought sarcasm just goes hand in hand with intelligence. Maybe that's just my proud, idealistic thought. Who knows?
