I know this is silly, it's shallow, it's bad, I wish I wasn't this way-but if I meet a girl with no teeth, I just don't want to date her. It's creepy of me, I wish I was a bigger person, but that's my real turn-off.
I just play to the people I can see. So it's almost like you are playing to the first few rows of the crowd. You can see the faces of the first hundred people, but then it becomes a blur as the crowds disappear over the hill.
Of course it can be said of jails, too, that they try - by punishing the troublesome - to deter others. No doubt, in certain instances this deterrence actually works. But generally speaking it fails conspicuously.
