Hi great definition of Extended Metaphor i.e." metaphors that are consciously (as opposed to out of necessity) sustained throughout a text or discourse (as opposed to isolated use).
I really like the idea of these stories and poems having these extended metaphors throughout and it works as a great new tool that we have learned i.e. “Dresses,” Bissonnette uses dresses to symbolize femininity, and the different stages of maturity that women go through during their lifetimes."
