Can't sleep

 I had too much coffee last night and after tossing and turning in bed for over an hour I decided I might as well get up and do the laundry... as one does in the middle of the night.  Load number three is washing as I type and with a bit of luck it can all go out on the line to dry in the morning. I'm a bit concerned about my walking buddy. Following her booster jab almost a week ago she is talking utter gibberish nonsense and can't think straight which is so completely unlike her. It's like watching a lady I once knew as her dementia gradually got very quickly worse. If she is the same tomorrow morning I am going to suggest she makes an appointment with her doctor although I have no idea what the doctor could actually do.
