Christine pearson and a colleague were studying the phenomenon of incivility along with their colleague. What we found is that it stuck and was much more painful than we would have anticipated. I remember incidents like, there was one person who had worked in a little league, a baseball a concession stand, and y he remembers being belittled. And 17 years later, he's writing about it and says he thinks about it. So you had people that were holding on to these experiences for months or years, but decades.
