Anton smiled, a bit surprised that she'd want to dance with him. She seemed older and somehow more sophisticated than he was - he didn't think she'd have much interest in a guy like him. But he was pleasantly surprised by the invitation.
"I'd love to - thank you. Just don't mind if I'm a bit rusty- I've done much more marching than dancing lately."
He set down his glass, stood up and offered her his arm politely to escort her towards the dance floor.
