every insensitive comment is a stone that you can polish into a diamond, that you can take with you to Olom Ha Boh.
do YOU know the truth of the situation?
why should you let someone else control your inner thoughts and feelings?
be strong, cling to Hashem, and let the comment pass
this is a great opportunity to overlook someones mistake against you, so that Hashem will overlook your mistakes against him.
dont let this opportunity pass by unfulfilled.
