- "Hurt expression" and "Absent apology" are contradicting each other. "Hurt expression" means an expression that shows hurt, unhappiness. Absent is defined in oxford dictionaries "(Of an expression or manner) showing that someone is not paying attention to what is being said or done", meaning that his apology was distracted, half-hearted, or perfunctory.

- Does "hardened bosom" mean her feelings and emotions lack sympathy or pity?
