Their sisters would take a combination of photographs and short videos on their smart phones. “Don’t forget boys, you’re only one click away from going public on YourTube or FaceBank…” they’d remind them. “…so you’ve got to be on your best girlie behaviour… we want to see smiles, not sulks.”

It’s a tricky path to tread. If they pretend to enjoy it, the secret is safe. If they’re sulky or stubborn or throw a strop, they risk exposure. They’re stuck between a rock and a hard place and there’s no getting out of it. Whenever Melanie insists on taking Paul to visit Audrey and Peter, there’s a strong chance that their parents will be out and that means one thing; girl time… again.
