Kens statement "dinner was being served" clearly paints the picture of the surprised cook placing steaming bowls of potatoes and beets on the dining table as Ken came banging in through the screen door..
No, Ken s arrival was not expected as since he also states " so I ate dinner and on setting on easy chair" so there could not have been a place setting for him at the dining table because Ken was not supposed to be there.
Ken has stated in numerous threads that he does indeed carry a cell phone always. He is a traditional man from a traditional background. Of course he carries a phone.
And there is still the matter of the 40 min time frame.
