Why only party on weekends?

When you can party every day of the week and annoy your neighbor with loud techno music, high screaming (girls), clouds of smoke and conversations in the hall (exactly in front of the neighbor's door). The neighbor is also very happy to be kept awake until the middle of the night since she is for sure not paid for not doing any work. But luckily the neighbor is used to the noise by now and has ear plugs. AND most important the neighbor is moving soon (already counting days).
