I feel like I'm being really awful in responding to gorgeous poetry like this, but I would very much appreciate an advance mention that I'm about to read a poem about not being able to breathe. I know perfectly well it's metaphorical, but I'm having a bad breathing week literally and, um, my asthma has psychological triggers sometimes. I don't want to be one of those people who can't read anything emotive without immediately commenting to demand cuts and trigger warnings and making it All About Them. So I hope you won't take this as a criticism, just a request if you can bear to flag up this kind of thing?
