Interesting evening. Dealt with a particular kind of rudeness, wherein, while constantly qualifying his statements, another person simply never allowed anyone else to speak, unless they shouted over him, or leaned in and got directly in his face. A serenely complacent attitude of "I am the only one whose voice, whose opinion, whose words, matter on these -- or any -- issues; therefore, I will speak, and you will admire me."

That would have been much more effective on me oh, say, ten years ago. But when it's being done to me now by a comparative stranger, who hasn't even given me the time to display my own intelligence or conversational value, it tells me, "Don't waste your time with me in the future." And I won't.
