The goal of this article is to point out a type of negligence that I believe is all too common: sociologists who totally ignore affects. During the investigation I myself involuntarily neglected those manifestations related to affects. Yet, they existed! They were perceivable, even obvious, during both observations and interviews; they were audible because the interviewees put these affects into words; both the interviewees and I experienced them. How are we to understand this negligence? How can we avoid it and what tools can the researcher use to mitigate it? We will try to answer these questions based on a field investigation of working-class parents whose child had been subject to a disciplinary sanction at college.
