I was having a drink at a friend's place on a roof terrasse in mid town, when I spotted a tent on another roof across the street. A huge party was going to happen there. Maybe we should try to crash in, said my friend. But I wasn't in the mood, and by looking on the right I saw a much more interesting kind of a greek temple on top of another building. No lights inside. They were probably going to the party…Was it going to be casual or black tie ? We never knew. We went down to grab some food in a nearby restaurant. The place was crowded and noisy. I left early, wondering what this party might have been.
