Rather than being the only true reconstruction of past experiences and events, the narratives constitute one possible approach to ordering them coherently. The labels used to structure these narratives must likewise be seen as provisional headings. As to the methodological validity of the narratives that emerge in this manner, it is important to see that the production process of narratives takes place on various levels. The first level is the level of the actual events as experienced by the experts involved, the so-called lived story (Rosenthal 2005, p. 27; Wengraf 2000) . Subsequently the experts themselves will reflect on these events retrospectively and from a certain distance. This level can be referred to as the told story. Finally, as a result of the interactions, post hoc reflections and reframings between interviewee and researcher, 2 the written story as a third level of narrative emerges 3 (Littig 2008, par. 17) . Thus, the written story builds on the two previous levels, and care is taken to secure the internal validity through iterative data collecting and interview sessions, as is also the case here.
