Spoke with Ma tonight.  She is in good spirits but fatigued.  No change with Father.  No new symptoms.  No results yet from the CAT.  She says the doctor was in recently and has gone to look at/for the films.  Mother will stay in the hospital with Father. She says they have a pull out bed and she can shower in the room.  As if she were on vacation:).
For those who are reading this and do not know; Ma and Pa do not have working cell phones with them in Costa Rica.  Nor do they have a computer.  Mother is using her iphone to email.  The phone is not working in their room.  It took me 4 calls and a lot of patients to get through to her via the nurses station.

Father told me when I was young, "Time is short, waiting is long" quoting some poet or another.
Mother says she will email when she knows something.
