Same story for the Netherlands I guess. We do house parties in our twenties too but usually it's for an occasion like a birthday, not just random having fun. T

Same story for the Netherlands I guess. We do house parties in our twenties too but usually it's for an occasion like a birthday, not just random having fun. There's also a lot of the 'meet around 9-10, have some drinks, light food and music at home until about 11:30 when you turn down the noise, all bike/taxi to the city centre and start hitting some pubs around midnight and stay there until the clubs fill up with people around 1:30 or so and stay until 4, maybe club-hop inbetween and then all go your own way home. The house party is more of a place to meet collectively, to get some drinks in 5x cheaper than in a club and talk to people while still sober and in a relatively quiet place, a pre-party really. By the 30s nobody really hits the clubs anymore (at 24 I've pretty much stopped already), plenty of parties at home though but usually there's no dancing involved which may tell you something about the nature of the party.
