In the chapter the author draws on new materialism and poststructuralism to write about becoming-subject. The author uses the notions of fluidity of the self, the (im)possibility of writing self and, at the same time, productive self-writing in the spaces between humans and between humans and nonhumans. She uses two encounters from her childhood to illustrate entanglements that highlight the ongoing production of becoming in the intra-relations between children and adults and between humans and the more-than-human vehicle-food-trees-snuffbox. The discursive Bmaterial encounters fold into and diffract out of her teaching and supervision practices in a counselling program in Aotearoa, New Zealand.
