No clue what to do....

Hare Krsna!

My mother is a devotee and she has a male "friend" who's a priest/vedic astrologist. He's out of town my mother cries over him, goes for tarot card readings, etc.

I've personally seen this guy watching xxx videos on my computer while he stays at or house, and hes known amongst his friends as unreliable. My mom knows this, except for the xxx part.

What should I do?

Hare Krsna!
