"Protect me from knowing what I don't need to know. Protect me from even knowing what I don't need to know. Protect me from knowing there are things to know that I don't know. Protect me from knowing that I decided not to know about the things that I decided not to know about them. Amen." That's it.

A peacefulness follows any decision, even the wrong one. - Rita Mae Brown

One day Alice came to a fork in the road and saw a Cheshire cat in a tree. "Which road do I take?" she asked. "Where do you want to go?" was his response. "I don't know," Alice answered. "Then," said the cat, "it doesn't matter." - Lewis Carroll
