My old person trait is that I think 'ghosting' is completely unacceptable and you owe the other person a face-to-face conversation.
I'm a historian and I would gladly talk at length to anyone about my particular fascination of the moment, no matter what they took or how high they are. I think I would even enjoy it more if a person was on psychedelics because they are way more open-minded and curious than sober people.
