She is laughing now too. ‘But instead my future was formed because I spontaneously went to Wales for a rugby match with my dad, only because I felt sorry for him as his brother had to cancel last minute. I was at a kiosk ordering a hot dog, chatted to Harry who was quite pissed and the rest is history,’ she says, in genuine wonder. ‘Like, if my uncle hadn’t had man flu, I wouldn’t have gone to that match, I’d never have met Harry, so what on earth would I be doing right now? Where would I be and who with? It’s weird, isn’t it?’

It is weird when you think of it. I’ve thought about it so often my head spins, but I’ve never actually had a conversation with anyone who thinks the same way about it.

I wonder all the time if I’d taken Tom’s advice that day when I sang for him back in 2010, if I’d had the courage to send out my work to record companies, would I be living in America now like he suggested? Would I ever have crossed paths with him again, would Matthew ever have had to hear his name again, would the accident have happened, would I have met Jack? One thing in life leads us to another and another and another – how much of it is really under our own control and how much is already mapped out for us, no matter how we try to change it?

Sophie sits up to pour us another drink, both of us lost in our own ‘other version’ of ourselves, and I feel a little dizzy. I stop her pouring mid-flow and she looks at me with a hint of concern.

‘You know, Charlotte, I also often remind myself that just because things could have worked out differently, doesn’t mean they’d have been better,’ she says to me, a little bit more serious now. ‘That’s what I tell myself anyhow. There’s no point worrying about “what if” even though it’s sometimes fun to wonder from time to time.’

I look at her and smile. She’s absolutely right. I briefly imagine how I’d be travelling the world with Tom had we stayed together. I’d be living out of a suitcase, I’d barely see my family, I’d find it hard to do something as simple as have a picnic in the park with a friend like I’m doing right now. It could have been fun, but that’s all it is now – something that could have been.

‘Yes, sometimes it’s fun to wonder,’ I agree. She continues to fill my glass to the top despite me stopping her seconds ago.

I love spending time with Sophie, and I love going home every day to Jack.

We clink glasses.
