I was on facebook and noticed that someone I was at university with was writing a book about something rather unusual based on someone he knew. I recognised some of the events so I sent him a message half jokingly and he replied saying 'oh I thought you wouldn't mind - I have changed the names and some of the sexual orientations.'
It feels weird - people from our group back then who know him and me will know it is me and he knows stuff about me lots of people don't and will put two and two together.
Am I being silly?
