Swamped

You need to calm her down. Right now, she looks like she wants to get out of here more than anything, which isn't conducive to getting information unless you can actually stop her from leaving.

"So... am I right about your name?" you ask, as casually as you can. "I had trouble hearing your answer over the crows."

No response. She's probably looking for an escape route.

"I don't suppose you have any idea how a swamphen got all the way up here?" you continue. You try not to sound accusatory, since it seems to have surprised her as much as you.

"I heard someone snuck one in to hide it from the rain," she says. "Maybe they left it up here. I dunno, why are you asking me?"

"Because you're the only one around to ask, of course."

There's a pause.

"Guess you've got me there," she shrugs. "Would you mind letting me send my letter?"

"To who?"

"To none-of-your-goddamned-business, that's who."

Well! That was rude, but she's at least settled down a bit. How should you handle this from here?
