Would you tell me whether I am right with my interpretation of the expressions in bold in the following sentences?
It’s hard enough for one person to keep a secret, let alone three. And then there’s the love angle. I mean do you and Sam really want that little pill-head around, now that you have the money?
I can’t take seriously one person who wears anything representing their commitment to remaining a virgin, let alone three.
Not many British bands these days have more than one million-selling album, let alone three.
let alone someone or something = not to mention or think of someone or something
love angle = love triangle
pill-head = an obnoxious person
Thank you for your efforts.
