[Chalky] It wasn't that weird, really, kind of lazy. She just wanted a couple of groups of people to stand around and get served canapés by waiters and chat. I assume the idea was that by putting me and my friends in a gallery we, and our social interactions would have been decontextualised so we became the subject of the viewer's critical analysis. Something like that.
Which, I have to say, is the oldest trick in the book, only slightly leavened by the fact that standing around eating canapés and chatting is exactly what looks natural in a gallery, so we'd have been decontextualised and contextualised all at once, which may be a bit self-defeating.
