Life is like a tooth At first we didn’t think about it, We just chewed And then it’s gone bad It hurts you, and we hold on to it And we treat it and the worries, And for us to be really cured We have to rip it off, life. (Boris Vian)

Those who know do not speak and those who speak do not know. The wise teaches by his actions and not by his words.
Lao Tzu
