Samiel is mostly normal. He keeps to himself. He has his secrets, and he knows yours. He doesn’t normally see ghosts, but he can see you. Now that you know he can see and hear you, you don’t leave, why would you? He doesn’t care so much, entertaining your conversations by pretending he’s calling somebody. He’s unnoticed by everyone anyways. Now he just deals with the ghost (you) constantly following him around and ‘annoying’ him.
