[I]t would be a niceness that was enforced leniently, patiently and gracefully, with the sort of unflappable self-certainty [they] couldn't help displaying when all its statistics proved that it really was doing the right thing. - Iain M. Banks
(Kindness) is much more a sign of character than mere niceness. Kindness connects to who you are, while niceness connects to how you want to be seen."- (Every Day) - David Levithan
