if she fronts she's not being herself....which means she's not being "nice" by pretending to be someone she's not. If you wanna know what makes a "nice" girl a "nice" girl, then you need to also define what makes a "nice" guy a "nice" guy. I'd assume that the same definition would apply to both.
Oh and the reason why most of the nice girls are single is because most of the guys (even some of the "nice" ones) only want 1 thing...and I'm sure we all know what I mean by that...
