It just isn't something good (IMO, so, don't take it too seriously), and it kinda hurts to see people choose to head into things that I think are at the very least not good and (usually, again IMO) straight up evil.
We're all adults here. You do you. I'm gonna stay far away from anyone that plays with tarot or other means of contacting random "spirits."
