I can't do it.

if grudge-bearing were an Olympic discipline I'd be decked out like ****ing Mr T by now.

and, other than a couple of ulcers and chronic insomnia through stress, vitriol and worry, I'm right as rain for it.

Im a pretty tolerant, forgiving person but I have a fine line. You cross it, and Im sorry but I want nothing more to do with you. I think everyone has a point where they just hold up their hands and walk off. I am not a vengeful type, I just stop caring.

Pretty much nailed it on the head. I find it a lot easier to forgive as I get older. Could it be that I'm just too lazy to hold a grudge?

Same here. I tend to react badly when I feel that someone has 'crossed the line' so to speak. VERY badly.
I would love to be able to let go of things, but it doesn't seem to be in my nature. I am NOT a very forgiving person. And when I do give someone the benefit of the doubt, I get screwed. So I'll just remain the su****ious, angry darling that I am.

i'm a card carrying grudge holder here. i'm like an elephant. or a rhino. or whatever it is that holds grudges . unless someone maajorly sucks up.
