I'm confused.

The granddaughter left exactly a week and one day ago and has not yet returned.  I am not sure if this is a normal occurrence or not; however, no one else in the household seems to pay much mind.  I think they must have noticed her absence by now; she always was a talker and there's a distinct change in the atmosphere.  I shall assume this is not something to get my feathers ruffled about.  However, I am a little disconcerted.
