One of the hardest things I struggle with is taking an insult from someone and simply letting it go. Proverbs 12:16 seems to speak directly to me, A fool shows his annoyance at once, but a prudent man overlooks an insult. While it may be a natural reaction to retaliate when wronged, it solves nothing and only encourages more trouble. Answering slowly or not at all are better options to end issues quickly and avoid unnecessary pain.
