" Lying is the oil that greases our interactions with others and lets us maintain friendly social relationship." P: 143.
I read a lot of interesting information in this book but I have found the above quote is the most interesting because it says explicitly that "Lying" is what makes our relations goes on! It describes the Lying as the "oil" that greases our relationships with words, facial expressions, and gestures. That's true!! It has limits and common acceptable boundaries in each society; if it exceeds the limits , it will become as the acid that erodes the metal! In fact, it is ugly to know that we are liars in a way or another! but without that we will end up alone!
