Absolutely too much

I just don't understand some people-sometimes when we are just being nice to them and what do we get?They treat us like somekind of rubbish!!Each and everyone of us has the right to be angry and ignorant but what's the deal when someone has already apologize for what they've done and trying to communicate with that person and all that they get is cold shoulder!
Some people just like and enjoy it when people beg them for several times over non-logic issues...who the HELL do you think you are?Many of us have our dignity and it's not just something that is priceless.This ain't no fairy-tale story so deal with reality....
