i'm afraid so. is that it then? haven't you brought anything else? small favours. the professor is unaccustomed to having children in his house, and as such, there are a few rules we need to follow. there will be no shouting' or running', no improper use of the dumbwaiter, no touching of the historical artifacts and above all, there shall be no disturbing' of the professor. you children are one shenanigan shy of sleeping' in the stable- oh, professor! i told them you were not to be disturbed. yes professor. come on, dear.
