Just shy of three hours? I anticipate this conversation will take another 15 minutes, perhaps a half-hour if we extend the social pleasantries. Then 10 minutes for you to get in touch with Sarah, an hour or so for a fight, an hour for her to pack and say good-bye, and then she's only a portkey trip away.
