I stop reading. Eventually. I mean my philosophy is that if the person at the door has left by the time I’ve arrived, I can’t say that I didn’t try – y’know? Although I don’t really live somewhere that people can just go up to and ring the doorbell. Usually the person that I can see through the peephole is someone coming to deliver the post, or my little sister. She’s either forgotten her key, or can’t be bothered to get it out. Sometimes it’s my mum coming up with the groceries. Then I run.
