Susie isn't old enough to go to school yet, but she loves to play house. She has a toy stove and she pretends to be a mother. Sometimes, when playing house gets boring, she goes outside, takes a garden hose, and pretends to be a firefighter. George Herbert Mead would say that Susie is:. a) in the play stage. b) in the game stage. c) her own generalized other. d) aware of the roles of others.
