Family surprise!! A couple of weeks ago on a Friday night, my son called and left a message: his wife had driven herself to the hospital at 3:30, it was now nine PM and the apendix was coming out at 9 (the 4th one that day for the OR) She returned to her grad school class on Monday.
I told my school nurse and she said the same had happened to her, also on a Friday night, but she waited 'til Wednesday to go back to work as a nurse on her feet all evening.
The wonders of modern medicine.
