On the other hand, without warning going dark for 4 work day hours a few days before exhibition would look terrible if any serious question came up.
So I don't think it's literally responding within the hour, but it comes pretty dang close. You have to keep in mind that being an artist creating art and being an artist setting up an exhibition are basically two different jobs and if you end up doing them in parallel at the same time, that's your problem right there.
