Geez, do you dummies take everything soooooooo literally? Yes, I literally meant every single mom - and that was internationally, btw - wore nighties driving their kids to school. It was a scandal for many years until the pc 1980s came along.
And yes, let’s forget about using an amusing word like ‘nightie’ over a dull word like ‘housecoat.’
It sounds like you feel you are above “us dummies” but Jims advise may do you good here and I am sure at home as you must be a real dream to have around the house.
