In my case, I wonder if I haven’t taken this a bit far. Ever since I moved into my flat two years ago, I’ve become disconcertingly dependent on the people across the hall. Gerry and Mary are, you may be able to guess, Irish. They are in their 70s and they look after me like the son they never had. Actually, they do have a son, and he seems very nice. But I’m just three metres away and worryingly available, which I suppose raises some questions about my own life.
