Can you tell others about the results of tarot cards?

Yes, of course, if you like. But if others don't want to, for the sake of privacy, it is better not to. But as far as the tarot card itself is concerned, it is a very approachable divination tool. There are no taboos. You are the owner of the card, do what you have to do, according to your wishes. Besides, if you can't tell the difference, those novices don't know how to solve the cards. Didn't they post on the internet and ask someone to cancel the card? So you don't have to be afraid.
