[Haldir... Don't tell Legolas that you can't dance?! What other reason would you have for refusing it?]

Is there a reason you wish not to dance?

[Goodness, Legolas is enjoying this TOO MUCH.]

Come now, you aren't shy are you? I assure you, were you to ask anyone in Mirkwood, you would find that there are few more talented a dance partner than I.
