This chapter focuses on the everyday in the cooperation between the AU and GIZ and examines how friction is made sense of by AUBP stakeholders. Drawing on sociological and anthropological approaches to studying IOs, it specifically looks at the role that the encounter between vastly different organisational cultures plays in the day-to-day cooperation dynamics. Moreover, the chapter studies the diverging organisational practices in the fields of human resources, financial administration and communication and analyses habits, narratives and shared (or diverging) understandings by peers of how things should be done, including by junior and mid-level career staff who have often been neglected in the scholarship on African regional organisations. Approaching development cooperation as performance, the chapter further analyses the backstage and frontstage narratives regarding this partnership and how each partner makes sense of the self as well as the other.
