Our sense of identity is in large measure conferred on us by others in the ways they treat or mistreat us, recognize or ignore us, praise us or punish us. Some people make us timid and shy; others elicit our sex appeal and dominance. In some groups we are made leaders, while in others we are reduced to being followers. We come to live up to or down to the expectations others have of us.
