"Oh darling...that's cute.  Do you really think anything you say will intimidate me?  Hehehe, you obviously don't know me well enough then."

Sasha (often more appropriately called Sass or Sassy) is a highly independent girl, not interested in playing by the rules or conforming to any sort of standard.  Societal norms?  Pah, they're lame.  Social standards?  Deal with it, sissy.  Familial expectations?  She has her own goals to chase.  She listens to no-one, respects few and is well known to everyone as a result. The local dog catcher can often be seen trying to stake her out, only to be predictably out-witted by the fox-like female.

Growing up a street mutt, Sasha learned to take care of herself from a young age and this lifestyle has definitely shaped her selfish, egocentric outlook on life.  She's used to only having to look out for number one, and can't handle commitments or responsibilities as a result.  She lives day by day, getting by on what she can scavenge or steal.  It's not a life for many, but to Sasha it suits just fine.
