It begins gradually,
First, a hello then an enquiry into all things you. Then a continuous conversation. He weans you off yourself and induces a conditioning that makes you reliant on him.
Then he infiltrates your thoughts, and turns your mental energy solely in his direction. Finally he does the right things, he smiles, he holds your hand, he’s there when you would otherwise be alone. Then you realize yourself is not yours anymore because you can’t feel without him.
This was a gradual process you did not see coming and it might be sublime or end in anguished chaos. You wonder how you got to this point; His nature made him do it.
