The criticism can reveal itself as contempt for you, your habits, your life, or your mere existence, and can also go a step further with humiliation. It may be framed as mockery in front of others, and downplayed as a joke, but it may also be indirectly communicated through non-verbals such as eye-rolling. Shaming and embarrassing you is an unconscious way for the narcissistic person to eliminate their own shame by pivoting it to someone else.
