If a question is dropped inside a statement or question, put a pair of dashes around it and a question mark after it.
…He was standing near — were you aware of him at the time? — the desk of the boss.
…I am going to read to you — can you hear me? — from your deposition of yesterday.
Do not cap after a dash unless the word ALWAYS has to be capped.
Grammar class starts tomorrow. It is not too late to join us.
Happy punctuating!
