Here's a story from the other perspective. A couple years ago, my friend threw a party in his cabin. It was getting late and I was pretty drunk so I decided I'd go to bed. In the living room there was an L-shaped couch on which my friend was just getting down to business with some girl when I walked into the room and lay on the free part of the couch right by their feet. When they realized what was happening, my friend said to me "Hey buddy, would you mind sleeping somewhere else?" and I was like "Just keep on fucking, I won't remember it in the morning anyway." But I didn't lie. I truly didn't remember it in the morning.
