There were only the three of us left after the party; my wife, neighbor, and I. All of us were drunk and nearly out of it. In the living room, my neighbor seemed to think that he and my wife were the only ones that were there. I watched him crawl to where she was half sitting and try to have sex with her. She was just watching, eyes almost closed, and not doing a thing. I could have stopped it, but didn't. He finally managed to begin and a short while later, he was finished and collapsed on top of her, both of them passed out.
