This is not the fault of women. This is the fault of men. Women play stupid mind games because GUYS KEEP FALLING FOR IT. If she knows you'll fall in line when she acts dramatic and stupid, then obviously she'll keep doing that until it stops working.Not all chicks play mind games though ....
That said, most of them do, and most of them do it whenever it plays to their advantage, which is most of the time ....
It's just like those guys who train their dogs to act stupid and train their kids to be annoying. Child wants toy. Parent says no. Child screams like a retard and makes a huge scene. Parent buys the toy. Lesson: making a huge scene = toys
