If you’re jealous of her, then rant to yourself. Words can be a passing thing or a lingering memory. Don’t hurt her feelings, because if she tells Louis about your hurtful comments, Louis won’t like you, and you’ve failed at getting to him and you’ll never have a chance with him.
It’s the same with Danielle!
And even Caroline. Yes, what she said was wrong and offensive and rude, but Harry liked her, so it wasn’t necessary to sink to her level.
