I'm starting to think there's a very fine line between trying to relax, calm down, and breath deeply (whilst not waking the person half lying on you). And hyperventilating because you're panicking in the middle of the night, in the dark, and don't want to wake anyone.
I'm not sure which side of the line I'm on.
But concentrating on hitting these tiny keys on my phone is helping.
John's probably dreaming that he's back on medical training, treating an asthmatic.
