From their earliest years, a girl is taught to communicate, while a boy is taught to hold his feelings inside, not display any emotion. I have often wondered whether these characteristics come from, where the child learns them. As I thought about it, I saw that the child's toys have a very large role in their, the child's, personal development. These toys come into the child's life at an important time. The toys become symbols of what the child wishes to become as they search for an identity.
Parents play a pivotal role, as well.
They from the start, treat each child differently. Everything from how they talk to them, to how they hold them. Girls gently, boys more physically and roughly. Each child is played with, in a similar fashion. In the end, when the child sees how it is supposed to act, its own behavior is set.
