This is an excellent book. From its marketing, I thought that "When Cultures Collide: Managing Successfully Across Cultures" pertained specifically to dealing with people of different nationalities in the business place. And indeed, it is a most useful book for that purpose. However, I was struck by how much one could apply Lewis' analyses to other situations, for example, dealing with people of other nationalities on a social level. Indeed, I have many aquaintances, and some close friends, from diverse backgrounds, and this book sometimes occupies us for entire evenings, discussing our experiences with one another. The chapter on Hungarians I found particularly accurate, and entertaining. I believe that Lewis would have enjoyed hearing some of these discussions (and arguments). My point is: don't dismiss this book thinking it is a businessman's tool. It's a good read for anybody who encounters people of other nationalities and cultures, irrespective of the context.
