Don’t expose your sore finger, or everything will knock against it. Don’t complain about your sore points, for malice always attacks where our weaknesses hurt most. Getting annoyed will only serve to spur on someone else’s enjoyment. The ill-intentioned are searching for a pretext to get your back up. Their dart-like insinuations aim to discover where you hurt, and they’ll try a thousand different ways until they hit upon your most sensitive point. The circumspect pretend not to notice and never reveal their troubles, whether their own or their family’s, for even fortune occasionally like to hit where it hurts most, and always cuts to the quick. You should therefore never reveal what causes you pain or pleasure, so that the former may quickly end and the latter long continue.
