The roles that males and females may also vary -- although a woman biologically gives birth to a child, a man may assume more or less care for the child, depending upon the situation of a couple.

First, the "social learning theory": relationships that are "more intimate" and that are developed "earlier in the youth's experiences" and thought to be more important; and youths are more likely to "imitate the smoking habits" (or non-smoking habits) of those with whom they have the closes
