two different ways:
1.)sensitive caring person: try your best to take all the shit and ignore it.
2.) my way... be more rude/mean than them... i could help you out if you gave me some specific situations. i dont think anyone has ever been rude to me, and me not completly ruin their day by either making them cry from words, or cry from beating their ass then runnin before the popo show up... those russian popo are prolly harsh... stick to words.
