I'm pretty sarcastic, the ironic thing is I have trouble catching sarcasm sometimes. But that's normally because people don't change the tone of their voice to be more sarcastic, so I assume their being serious. You feel me?
A lot of people take pride in their sarcasm and wear it every waking moment. This makes them totally unbearable to be around because they want to correct everyone all of the time and prove that they are more smart than everyone they are around. In the end, they wind up looking like anti-social fucks because no one wants to be around them.
