Social Construction of Gender

Think of a toy that a girl would want for her birthday. Now think of a toy a boy would want for his birthday. Are they the same? Probably not. A girl toy you thought of probably is related to dolls or a kitchen, while a boy toy has something to do with transportation or fighting. There is nothing stopping a boy from playing with a doll or a girl from playing with trucks, besides the social construction of gender that has come about the past several decades. Because of this social construction starting at such a young age, before the kids can realize they are being taught "how to be a girl or boy", they become used to the toys they are expected to play with.
