I'm not sure if anybody has this experience of dealing with patronizing and busybody neighbors. Years ago we moved out once because of inconsiderate neighbors ganging up on us, problem solved for the time being.

Years later, the new neighbors living opposite our apartment start to pick on me for little to no reason.
They would often hide in an area unnoticed, waiting for me to appear in a noticeable position in our house and start to call my name, make patronizing remarks, mockeries and taunting sounds.
Seemingly trying to ridicule every aspects of my appearance, demeanor or whatever move I made.

I dealt with them in kind by making sarcastic hand gestures, but they seem persistent on pursuing me, and hell bent on provoking me to the point of getting into trouble or move out. I suspect the old neighbors are one of those behind this.

How do you deal with such people?
Appreciate any inputs.
