did they explain why she was grunting, rather than just speaking in her natural southern accent?  if joster wants a date with a girl, he could definitely try that, but they won't open up to him (start talking) until they decide he's not creepy, hence it's necessary to interpret their body language and facial expressions with lightning-like speed and absolute precision, as they will decide whether he's creepy in the first 6.5 seconds.  YMMV.
