Why are we drawn to those who are cold?

Have you noticed how strangely attraction works? We feel attracted not to those who are open and accessible, but to those who seem to keep their distance. Coldness is a challenge. It creates excitement and a desire to break through the ice. A man encounters not a body, but a wall—and this makes him dependent. The less a woman reveals herself, the more he thinks about her at night. Unavailability becomes an aphrodisiac. Sometimes, in a relationship, it's not warmth that's more important than the right dose of cold.
