If a man throws a stone at you, is it better to throw stones back or is it better to just walk away?
Throwing back would bring you down to their level. Walking away often makes them look like a butt head. Throwing back can start a real battle with the outcome of both being hurt or maimed.
Same goes if someone says something hurtful to you. If you do nothing more than saying hurtful things back the only outcome is that both of you hurt and quite possibly will go on feeling bad towards each other for a long, long time to come.
The easy way is to say bad things back. The tougher way is to just turn and walk away.
Something my dear mom taught me when I was very young.
It takes more of a man to walk away than to stand and fight.
