There is no point in postponing this any further; we are going to go ahead and have a house party in a week or so.
Monica-Sophie is presently in South Korea and will be in town for a couple of days before leaving for Budapest, possibly up to a year; Valérie will also be here 9in fact, she's been here all summer), so this seems like the best time to invite people over, whether the house is messy or not.
