When you don’t apologise IMMEDIATELY for doing something wrong, you show WEAKNESS
When you don’t apologise EVENTUALLY for doing something wrong, you show WICKEDNESS
When you expect the person you wronged to apologise, you show DEVILISHNESS.
It is not that those who don’t apologise are never WRONG. Rather, it is that they are WRONG people. Because to ERR is HUMAN and to FORGIVE is DIVINE. Thus, if you never apologise, you are claiming DIVINITY. And that is the sin that destroyed satan!
