Well I did brace up for a though conversations with a friend at a point and most times I feel it will have been better not to talk when one is angry or the mood is very bad, we say alot of things we do not mean and there is no way we can take them back, they cause more harm than good.
But passing bitter feud to the next generation is totally out of place.
Forgiveness might play a role here, forgive forget and live peacefully with the other party no matter the bitterness we nurse towards them.
We can never convince others to think like we do and even after a hard conversation they still may not come to our terms, we move and live past that experience.
