don't react -- own that you have boundaries, HEALTHY boundaries
and stand firm in those boundaries; if pressed, be polite
and if that doesn't work, shut the door
this is especially true in "Psychic World" -- own your truth, own your work, own your right to set boundaries
be polite -- but shut the door fast
and don't look back
and, more importantly, don't question the legitimacy of shutting the door when you feel it is appropriate
