Such as.... 1) don't shit in the hand that slaps you as in your
parents because they
slap you with that hand by controlling your existence. 2) don't shit in the hand that slaps you as in your boss or supervisor because they control raises at review
time and promotional futures. 3) don't shit in the hand that slaps you if of your wife or girlfriend because, well, we all know what she does with that hand don't we?
