You can wear a white T-shirt to a water park. Car mechanics tell you the truth. You don't give a rat's butt if someone doesn't notice your new haircut. The world is your urinal. You never have to drive to another gas station because this one's just too icky looking.
Wrinkles add character.
People never stare at your chest when you're talking to them. The occasional well-rendered belch is practically expected. New shoes don't cut, blister, or mangle your feet. One mood, ALL the time. Phone conversations are over in 30 seconds flat.
