Every once in a while, I encounter something written so well that it is impossible to improve. The only thing is to wish it was mine and send readers to it or steal it. Much as I wish I had said this as well as Fr. Nick did, I am simply refering you to it:
Fr. Nick's blog I wish I had written this.

Go read it, trust me. If you comment there and you probably should, please tell him I sent you. ;-)

FWIW
