Once, while out drinking with my brother, he invited a girl over. It was my first day meeting her, and after some drinking, the atmosphere got a bit flirtatious. Later, as she was too drunk to go home on her own, my brother, who said he had known her for two years, suggested we should help her to his house to sleep, and without thinking too much, I agreed. It turns out they got together that day. So, was I just being a complete fool?
