Xerxes: Come, Leonidas. Let us reason together. It would be a regrettable waste......it would be nothing short of madness were you, brave king......and your valiant troops to perish......all because of a simple misunderstanding. There's much our cultures could share. Leonidas: Haven't you noticed? We've been sharing our culture with you all morning.

Xerxes is trying to convince Leonidas that the Spartans really shouldn't try to fight the Persians.
