You were a dear person to William. He tried to care for you and showed signs of affection. He used to come round to your house for tea and you'd have heart-to-heart conversations.
On the face of it, all was well and all was peace, friendship, chewing gum, but there was always one thing. You were trying to hurt yourselves. And William knew about it and was very concerned about it. He told you directly that it wasn't the best way to ease the pain, but you wouldn't listen. After that, he got a little tired of trying to influence you and stopped trying to get through to you.
It was half past five on his watch and he decided to pop round for tea and biscuits as usual. He was walking down the street and when he got to your house he knocked on the door.
