Your Face Tomorrow: Fever and Spear - pg. 176

Some people can't forgive you for behaving decently towards them, for being loyal to them, for defending them and giving them your support, let alone doing them a favor or getting them out of some difficulty, that can, on occasions, sound the death knell for the benefactor. I'm quite sure you can come up with your own examples. It's as if they humiliated by being the object of someone's affection and good intentions, or thought that this implied a degree of contempt towards them, it's as if they could not stand to feel indebted, however imaginary the debt, or to be obliged to feel grateful. Not that they would want to be treated otherwise, of course, heavens, no, they're always terribly insecure. They would be even more unforgiving if you behaved badly or disloyally towards them, if you denied them favors and left them firmly stuck in their own mire. Some people are simply impossible, and the only sensible thing to do is to remove yourself from their presence and keep them at a distance, and not to let them near you for good or ill, or count on you for anything, quite simply, to cease to exist for them, not even in order to fight them.
