LOL! Actually, the engineer was fine - a rather lovely man actually; it was Dad asking 'why is he here?' over and over and over, then getting up on a chair to meddle with the thing, when no one was around and falling off the chair and almost breaking his neck that caused all the angst.

As for the hoovering... I'd really rather not even talk about that. ::is drawing a mental veil for the sake of sanity::
