2. Speak boldly against persistent put downs
Sometimes such people have no sense of self respect; so much that they will repeatedly try to pull you down to their mental level. In which case, simply ignoring them won’t send them away.
Particularly when they are around other people, they’ll want to provoke you into some kind of reaction.
You should confidently tell them to stop that kind of behavior and address you respectfully. Being assertive shows that you’re not moved by anything but a decent exchange of facts and opinions.
You show that you can stand your ground and defend your beliefs, opinions and dignity in a constructive manner.
That positive, forward-looking attitude has the power to dissolve situations that could otherwise rob you of your self confidence.
