The ugliness of truth - pt 2

I should just clarify:
I do not believe that lying is the way to go. I don't practice or advocate lying. I am referring to things like:
  • Thanks, what a lovely meal... when it was pretty average
  • Getting up for someone older (on the bus) but doing it with a little bit of resentment towards someone younger than you who did not get up - but not causing a scene
  • Blessing a sneeze - but not meaning it
These are simple social graces that infills the yawning gaps in the ugliness of beauty- without which we cannot function; because truth is just too ugly.
