I just listened to Episode 3 of the Liminal Lounge podcast.
One of the things that I am constantly asked by others is, do I approach people in the public to say I have a message for someone? I do not because I do not know how open people are and I feel like it will drain my energy.
But in the podcast, they made a good point about the sitters point of view or ethics. They may not believe in an after life and if you were to approach someone, it could quickly cross a line.
