Yea I kind of experience this process myself. I don't hold a grudge unless I know intentions were proven to be with ill will.This is not a grudge, we bear no ill will (intrinsically) unless we know the damage to us was done with malice aforethought. Otherwise, it is merely efficiency in self-preservation.
The reason third chances are not given is simply that we know by that point, that further chances will be useless, and will only result in additional (foreseeable, therefore unnecessary)
harm to ourselves.
Except I probably have a lot more endurance cause my Ni is not as up to par with the patterns as an Ni dom's.
