He ignores her question. ‘So what about you then?’ Clearly, he’s ready for this conversation to change direction. She can’t blame him for that.

‘Greg,’ she lies, without hesitation, because telling the truth is not an option. ‘Maybe it’s always the men who love larger? Now isn’t that funny?’

‘Can I ask you something?’ Rob says.

‘Go ahead.’

‘Why did you suggest this?’

She looks at Rob and knows that she will never be able to tell anyone the truth. ‘Because I want to feel alive.’

It’s to be expected that she’ll be a physical wreck the next morning. Those days when she could party all night, waking up bright and fresh after only a few hours’ sleep, have long since gone. Somehow, she manages to clean up the mess in the garden, and with every bottle or glass she transfers to the recycling bin or dishwasher, she marvels at how only four people could produce such a gargantuan mess.

Rob has already left, having the excuse that he was desperate to shower and get into clean clothes. He’d declined her offer of something of Greg’s to sleep in, saying he’d make do.

Being in the kitchen with the sun streaming through the doors, it’s hard to believe this is the same place where last night everyone had gone along with her suggestion. It’s too late to be undone, but now she fears things might be different between her and Abby. They have seen each other’s husbands in a way that they never would have normally, and there will always be those missing hours in their marriages, long moments shared between their partners and someone else. Something they will never be part of, even if they recount every detail.

Greg has already left Abby’s to go to the hospital; Sienna found this out when she texted him the moment she woke up. He needed to catch up on paperwork, he’d said, even though it is a Saturday.

It feels strange that she hasn’t seen him since he left last night with Abby, and that she isn’t the first person he saw when he woke this morning.

She can still picture him walking out of the door last night with Abby, with barely a glance back, as if what they were all doing was the most natural thing in the world.

She’s tried calling him several times already, only to find his phone switched off. She’s also sent Abby a text, but she’s yet to reply. It’s nothing to worry about; they’re not avoiding her. This is just paranoia, and she must control it. Greg will be home eventually and then she’ll see that everything is normal. A normal that she knows has to change.
