In spite of himself, Derek snorts in an effort not to laugh. "Wow, we're a real pair," he sighs, rolling his eyes. Neither of them appears to have a whole lot of control over the words coming out of their mouths and, worse, it doesn't seem to be showing any signs of decreasing intensity.

"I'm sure you can," he adds in response to her comment. "I'm just trying to be polite." Then, before he can stop himself, "my mother raised me to be respectful and helpful, especially to women. So I was just trying to help." And now he can't shut up, so there's that. Which is, you know, great.

Derek clears his throat as they head inside. "Anyway, you're welcome."
