I am visiting our former colonies on the other side of the pond in about ten days' time. I am beginning to get a little concerned - will I understand a word they say?Don't sweat [ whatever ] can be an idiom to mean "Don't worry about [ whatever ]."
As in, don't sweat the small stuff, don't sweat this project, etc.
