This can be a bad advice when the one who knows his rights meets someone who gives a shit. If you are not serene as a jester, not friendly as a priest and not cool like a poker player, you might get yourself into a situation you wished you never would. There is the right things to do for the right moment and estimation. But if the estimation and moment is wrong, you can lose a lot more than you can win.
I can do the right thing but I might regret in doing so if I am not acting out of faith but out of something lesser.
