On the other hand, girls prefer to host and attend pretend tea parties. But why do these differences W exist? Advanced Several months after babies are born, female babies like to look at a person's face to read emotions while male infants prefer to look at objects. Few would disagree that men care more about objects while women tend to empathize with others. However, the sex of our brain is not always as clear-cut as the sex of our body. In one experiment, a tough man, who seemed very competitive, was shown to possess a high degree of empathy, while a woman scored the highest in a hand- 10 eye coordination test at which men were thought to do better. This shows that the distinctions that set us apart might not be as clear as we think. 5 I t ZAN Differences between the sexes are hard to understand and so are relationships. What on earth makes people fall in love?
