One of the best reasons to throw a party is that it forces one to clean their place. I should have parties more regularly because it gets me to clean. I’m trying to encourage my friends to be more willing to drop by unannounced; the threat of people seeing an untidy place is quite motivating.
So, after throwing a wild potluck party yesterday, (where the last person didn’t leave until 2:00 in the morning) and proactive tidying, my place is cleaner now than it was two days ago.
