In my current book, the main character is a knight and in one of the beginning scenes, he interacts with the princess. He's intimidated because of who she is (royalty) and acts very formal around her (never calling her by her first name, etc.). There's a scene with just the two of them before they know each other. my question is, what kinds of things can I have them say? I'm kind of hitting a block. In my head, the characters are both sitting there awkwardly because I cannot think of a single natural thing for him to say. Any ideas? (Again, he acts very formal and polite around her, because she's a princess.)
How can I make this scene? I need some ideas for dialogue.
EDIT: The knight is kind (not shallow/vain or overly courageous, just a typical boy who was drafted when he was young and trained to serve the kingdom) and not typically shy, but he doesn't know what to say around the princess. I think this is where my problem lies. I don't know how to make their conversation happen when he doesn't feel like he can talk to her without being "improper" or whatever.
As for the romantic interest, the princess is interested in him because he's different than the men she is usually around. When he was drafted to be a knight, he came from a farm. So he's very different from the boys who grew up in the castle. And, he has a girl back home, so he's not interested in the princess. He is nervous/stiff around her because of her status.
