Having left childhood behind, these chicks now battle through their twenties. Here they are buffeted between the pressures of work, drinking, boy-friend merry-go-rounds, monthly hormone attacks and the belief that their clocks are ticking.
Believe me, one day these chicks are heaven sent babes, then on the turn of a penny, the next day they are knife wielding harridans who relentlessly chant the mantra "All men are bastards ... why can't I find a boyfriend ... I'll never have babies ... I don't need a man etc."
Avoid them while in this evolving stage. Good news is they normally get their shit together sooner or later and the story does very often end happily.
Remember that every milf once was a psycho chick.
