Why don't you talk to strangers after burning paper at the crossroads? Why?

There is a saying here, which is actually the case. When burning paper, there is a saying that you burn paper with someone in your heart, and only that person can take the money. If you are insincere and unstable, it will be broken. Not only the person you want to burn can pick up the money, so can others! (Of course, people here are people there. ) In this way, ghosts will come to rob money and burn paper to talk to you about your god. Besides, when you burn the paper, who in their right mind will come and talk to you? This is at the crossroads, not at the grave.
