During the dancing it was like a feedback loop of emotion, the happier and more relaxed Ben became the more excited she got up to the point that Sadie was having to dedicate a part of her attention to consciously not give in to the urge to loudly purr as they continued. At least until the rude man causes Ben's rhythm to to stall.

"Rude fucking wanker," Sadie scowls at the back of the rude man's head before turning back to Ben and trying to coax him back into the dance, "Ignore him, it happens all the time at clubs and he was just being a twat about it."
