I know I’ve become a bit obsessed, and I think I should pull back a bit – but she seemed to be enjoying our friendship and getting closer. Maybe I’ve misinterpreted her, but I don’t think so. I am usually good at knowing if someone likes me or not. I know that Michael did, and Sam – until things went wrong. But when relationships are so intense, things do go wrong – I realise that. I just don’t want to blow it with Carrie.

I decide to leave her to it for a bit, wherever she might be.

I sit up in the bunk and pick up my phone from where it’s been charging on the small table beside me. I open Facebook and have a scroll through my feed, but there’s nothing much of interest on there. I don’t have enough friends for it to be particularly interesting, preferring instead to look at individual profiles, especially those who have everything set to ‘public’ – which is a surprising number of people, despite all the warnings about online safety. Sometimes I send random friend requests, if I find someone intriguing, but I usually delete them before they get accepted or ignored. I’d prefer not to be rejected, but also I prefer not to have them question why I am sending the request. I have had that a few times. I’ve learned my lesson.

I check a couple of my usual profiles, but nothing much is happening. Maybe because of the time-zone differences, I’m missing out on the new stuff. I consider ignoring him, but I know I can’t stop myself looking at Sam’s profile for updates.

He’s at a street market. Him and two of those German lads, gurning, grimacing faces holding insects up to their mouths. I click on a video clip and watch one of the Germans eating a live cockroach, his face joyous at first and then a look of sheer horror, before he turns away from the camera and vomits, while the others laugh. I don’t think it’s funny. I stab a finger on the app, shutting it down. I should delete Facebook from my phone. It really doesn’t make me feel good.
