what i mean by that pruni is that the things that hurt us are thing that tap into our own often secret beliefs about ourselves.
for eg, if you KNOW that you are a generous person, then being called tight might irritate you, but isn't going to hurt and make you angry in the way that it might if you kind of believe that sometimes you are somewhat ungenerous.
if you are aware that you are tight and the reasons why you are, again it can't hurt you as much. so the more self aware and honest we are with ourselves the less we buy into the horrible things that people can say, or at least if they are true we've come to terms with that aspect of our nature.
to my mind, it's not an excuse for being horrible to someone but rather it's about realising that we are vulnerable in ourselves not because someone has made us that way with their comments...does that make any sense at all whatsoever????
