My juniors in training describe every male patient as a gentleman. I tell them there are men who’d be offended to be described as a gentleman: you risk being rebuked with “I’m no gentleman. I worked for a living.”

No need to be sorry, one day you'll have a photograph to share or a link to a photograph, then you can show off.
