Abstract
When I asked my past interviewees to check their drafts and permission for me to publish each case, a male informant asked me not to place his case in the book because of the feeling that something was wrong. The point, which caused such a feeling, was due to the fact that I had minimized him to the category of 'the eldest son' and depicted his life story so simply by using this category. The factor of being 'the eldest son' was not the essence of his story telling, but it was the keyword of the researcher to analyze from the viewpoint of gender. His complaint taught me what kind of a risk that a researcher generates by using social categories based on selfish motives.
