I did the phone chat and crossword with my elderly friend M again this morning. We make a good team. M knew the word "etui" for a needle case. I'd never heard of it before, despite having had a mother who sewed a lot.
etui a small ornamental case for holding needles, cosmetics, and other articles.
"exquisite etui cases fitted with scissors, bodkin, and thimble"
I, however, provide the answer to clues like, "A Mexican snack." Answer: tacos, something M had never heard of. Or the other week the answer to a clue was "jpeg".
