I’m really enjoying this book a lot. It’s facinating. I also find that I can’t helping smiling throughout the whole thing! The book is divided by different types of smiles. I just finished the chapter on lewd smiles. The writer talks a great deal about how hard it is to figure out what makes one type of smile what it is. We recognize lewd grins, but how are they physically and visually different from, say, grimaces? Is it a lewd grin simply because of what else the person’s body or personality or something tells us? It’s a facinating question, and one I’m not sure we can ever really answer well, since we can’t remove context very easily when it comes to smiles.
