If you are asking for "SORRY" for all the mindless things that you have said and done, and you expect that everything will be forgotten and forgiven just because you said SORRY, you are in for a big surprise.
In the heat of the moment, you said those unkind words, and the wounds you inflicted have maimed and ravaged the person emotionally and psychologically and you expect the trauma to evaporate in thin air and the cuts will just be healed just because you said SORRY?
