Walking out leaving an important question unanswered isn't the sign of a tortured soul. You make it through a career and retirement is weeks away it is careless and lazy. This, if we accept that your perception of things is accurate, (appearances can be deceiving), not that we should doubt you just that there are unknowns. I had a cardiologist who was set in his ways and slacking off. He said retirement wasn't in the cards (his words) then months later the hospital announces his retirement. I didn't complain through a formal procedure but people around him were involved in correcting a sloppy error handling my case. There probably were other instances with other patients.
