Sometimes when we feel so abused... so hurt... so betrayed... and so mistreated... the pressure of "being good" and being a "real friend" become far too great for an overly taxing situation. Those who would criticise us for this pressure are usually the ones who put it there in the first place by asking us to bottle it up and demanding the silence.
... These people are far more selfish than those who they claim to be selfish.
