Dawn and I, on our seven mile hike she was bragging about earlier, were talking about what a social retard I am because I've trained myself to be a conversation ender. It's necessary, for me, working behind a bar, to know how to tactfully and subtlety get into and out of a meaningful conversation in the time it takes me to pour a beer. Now I do it subconsciously, bring a dialogue to an end without meaning to, but all of a sudden there is nothing left to say and the only option is to walk away. That's what I do most often: walk away from awkward situations of my own making.
