Yesterday, as I sat on the train to Brighton, I couldn’t help but overhear a conversation (they were almost shouting) between two people (a man and a woman) who were comparing their drug habits. They seemed proud to have been addicts for more than ten years, and derided someone, saying “she’s not an addict, she’s only been a junkie for two years”. And they didn’t have a good word for the “filth” and the “screws” either. How strange to discuss this in such a way and in such a place.
