OH now that is funny! The "ne'er-do-well" comment.
I used that term not too long ago at a morning meeting. My supervisor had no idea what it meant..
I had to explain to him the meaning of the term.
Then, not 24 hours later, I was talking to a Doc friend who asked me if had pointed my pistol at any ne'er-do-wells lately.
I just started laughing and told him that apparently not too many people used that term any more.
