From my "Words You Should Know" book:
misanthropy: hatred of mankind
That was me yesterday. I was soooo antisocial.
mellifluous: flowing sweetly and smoothly
That's me today! I'm in a MUCH better mood!
blather: to gabble or talk ridiculously. To discuss meaningless issues for extended periods.
That one's just a fun word. And yes, I do talk a lot, but it's never meaningless. I swear.
