My sister talked to Dad again.
Her email follows.
He’s in fine spirits in spite of the hospital staff not being able to meet his needs for insulin. He said he knew that would happen and resigned himself to being an interested observer when he knew he was going to have to be admitted. When I spoke to him he had returned from having the cardiac stress test, the results will not be available until tomorrow. He commented that they seem to have forgotten about his toes – the reason for the hospital stay initially- in favor of his heart… can’t say I blame them… and expects they’ll get back to the toes soon.
