Where all think alike, no one thinks very much.

Walter Lippman
1889-1974

Well, I do not completely agree with this but there are cases where it is particularly apt.

But then you can never really make it into a black or white case. Where people are concerned, there are a lot of gray areas. I guess that's what makes things exciting. It would be a big bore if you could predict completely what would happen. No fun at all if you know everything beforehand, is it?
