Most women had the one thing in common: they had great pain when they gave birth to their children. This should make a bond that held them all together
 it should make them love and protect each other against the man-world. But it was not so. It seemed like their great birth pains shrank their hearts and their souls. They stuck together for only one thing: to trample on some other woman... whether it was by throwing stones or by mean gossip. It was the only kind of loyalty they seemed to have. Men were different. They might hate each other but they stuck together against the world and against any woman who would ensnare one of them.
