Sarah didn't want to argue with him anymore, especially after he mentioned his mother and took her words over her again without answering her questions. She was tired of listening to Charles' excuses and didn't expect him to be so persistent to question her. She really hated talking with him like this, especially in public, so she shook off his restraining hand and said firmly. "Charles, I've already answered you, so please just stop, ok?"
However, Charles didn't let go of her. "Sarah, are you really that cold-blooded? I've done so many things for you, haven't I? Don't you realize that?"
Sarah didn't want to hear him and didn't want to continue arguing, so she shook his hands off more forcefully and strode away.
