I would not even call it friendship. If it comes to friendship there has to be a certain bond and I don't see or feel this bond. To me he is a stranger, someone in prison I once wrote but hardly shared a few lines with me. It's not my idea of a penfriend nor a friendship.
For sure he is lonely, confused, depressed, without plans for the future once out of prison. He has no family support or friends and he is on medication. So I understand he sees me as the light in his darkness but that is not love.

Once out of prison I am forgotten or even long before.
