When we're good at sarcasm, it creates the illusion that we are cool and suave and in control of a situation, that we have power, that we are the "insider" in the situation and the "outsider" is to be scorned. It strokes our ego because people laugh and think you're clever.
But truthfully, a person who relies on sarcasm is really a scared two-bit hoodlum backed in a dark corner, stabbing outward with a switchblade at everyone who comes near, without first even bothering to check if the person wants to harm or hug them.
KIRKEPISCATOID on sarcasm. Great stuff!
Mea culpa, of course.
