"My Lady, isn’t it time you came home properly announced, instead of skulking like this undercover?” Are these commas correctly positioned? Include an explanation please. Thank you. I think my confusion is because, if the commas were treated as parenthesis commas, either end of the sentence joined up would read. "My Lady, instead of skulking like this undercover." Just when I think everything is perfectly clear, I get another spanner in the works.
