I haven’t answered my phone on any of the occasions I’ve seen her name appear on the screen as it is ringing. Each time, I’ve told myself: don’t be stupid, it’s Jess, it’s only Jess. And once it has stopped ringing, each time I’ve promised myself I will call back, I have prepared myself for calling back, and once I have failed to call back, I’ve promised myself I’ll answer it the next time.
