When we are children, when we are young, it is natural to love our friends, to be generous to them, to forgive their faults.. But as we grow old and have to earn our bread, friendship does not endure so easily. We must always be on our guard. Our elders no longer look after us, we are no longer content with those simple pleasures of children. Pride grows in us - we wish to become great or powerful or rich, or simply to guard ourself against misfortune.
