Your talk shows your faults,it is like a sieve that seperates out the rubbish. the way you think shows your character just as surely as a klin shows any flaws in the pottery being fired. You can tell how well a tree has been cared for the fruit it bears,and you can tell a person's feeling by the way he expresses himself. Never praise anyone before you hear talk: that is the real test.

SIRACH 27: 4-7
