Kickass, the doorstop dog, indulges the keeper as he, and everyone else, suddenly are forced to focus on their personal health, perhaps recalling past threats and relating them to the current coronavirus situation.
The keeper and Phyllis, because of their ages, and in Phyllis’s case a compromised immune system due to cancer treatment, are particularly at risk; and their thoughts are obviously no different than those occurring in many households. They recall past health run-ins, and the many decades when their good health was as taken for granted as getting up in the morning. The keeper remembers the occupied body-bags behind a MASH tent in Korea when he sought relief there for crippling sinus headaches, and Phyllis thinks of the questionable quality of life led by her 97-year-old mother.
So these life and death matters intrude into their lives, and the time that the keeper and Phyllis share together becomes incredibly valued. It is, perhaps, the kind of thing happening to everyone around the World. Time is everything.
