My father is hard to impress, cares little about the arts & cares less-than-nothing about celebrity. He was fortunate enough to meet this classy lady many years ago, when she was searching for just the right specialist to treat a relative & it lead her to his hospital. 

The people accompanying her introduced her as Ms. Bacall. She shook his hand firmly & in that trademark smoky voice, she insisted he call her “Betty”. He said she asked great questions, really knew her stuff even though it wasn’t exactly in her wheelhouse & she left him a bit awestruck. 

I was impressed by that - so much so, the smartest character in my story [rapidly approaching novel status] is named for her: Betty.
