There is a classic quip called "There are only two people in the world." To put it more seriously, "men and women are in an eternal war." This means that we start grinding our teeth on our pillows as soon as we enter campus, and we will continue grinding them until we are old and have no teeth. Indeed, "things between men and women" are almost the most common theme among human beings. We were created by God out of different materials and had very different tastes from the beginning: women like mirrors, men, probably because women like mirrors, like weapons. And women probably like mirrors because they like men.
