"Sorry" teaches counterfeit apology. True repentance would involve undoing the wrong act. But when you knock an opponent’s piece off the board, and say “Sorry,” you never take it back! If you cut in line ahead of your brother, and say you're sorry, but you stay ahead of him, you make a mockery of your apology.
There are several elements to full repentance. Going to everyone you wronged. Describing the offense to the offended. Asking for forgiveness. Avoiding excuses. Making it right as best you can shouldn't be forgotten.
