'I know you and he are very good friends,' she continued, 'so I thought it was fair to tell you that. He's really interested in us starting up again. But I'm not.' She moved closer so our faces were only a few inches apart. 'That's why you're here.'

I wasn't sure what to say, so I plumped for saying nothing. Nor did I resist as she took me by the hand and led me up to the front entrance of the building, although I now knew this was going to be more than just an extension to our chat.

Inside, the foyer was empty, and I noticed Jenny frown as she swiped a card through the space-age-looking reader, releasing the lock on the double doors. 'There should be a doorman on duty,' she said. 'That's what we pay our maintenance for.'

I wasn't quite sure what you needed a doorman for if you had to use a key to get in the building, but I was pleased he wasn't there. I didn't want any witnesses to what I knew was going to be the betrayal of my oldest friend, especially if – God forbid – Dom and Jenny ever did get back together. Although to be fair, that wasn't sounding too likely.

As we got inside and she pressed for the lifts, I heard rapid footsteps coming from the hallway behind the front desk. It sounded like the doorman was returning, so as the lift doors opened I hurried inside and pressed myself against the wall, still worried about being seen.

Jenny followed me in, standing in the middle, and as the doors began to shut she called out, 'Hello, John, I thought you'd gone on strike.'

'Toilet break,' I heard the doorman call back, and then the doors closed, and she pressed for Floor 9.

We looked at each other for a long second and I knew immediately what was going to happen. She leaned forward. So did I.

The first kiss was hesitant, just like it always seems to be in the movies, and I felt my last twinge of guilt evaporating.

The second kiss was harder, longer, and I hardly noticed the lift doors opening again. We paused for a couple of seconds, then she took me by the hand and led me down a short corridor to her front door, kissing me once again before we manoeuvred our way inside, still attached to each other at the mouth.
