Just a couple of quotes from one of my favorite porn models (yes, I said porn models, get over it!)...
"Have you ever been dining at a restaurant and someone walks up to your table to introduce themselves or they are a distant acquaintance or whatever and they want to shake your hand? If you are that person who keeps extending your germ infested, butt picking hand to some poor diner who is just about to lift a taco to their lips, STOP IT, dammit!"
"If people spent more effort working on their interior qualities such as character, personality and integrity, instead of nitpicking every perceived flaw on their exterior, then this world would be a much better place."
