Smile for the camera

Smile, when your thoughts turn snide and you don't have a good word to say. Smile when you know it's dead but carry on all the same just to keep up appearances - to avoid disappointment. Smile when you're about to run but then consider your social standing and skip instead! Smile when you've had enough and want to practice your frown.

Smile when you're pissed off and annoyed, not because of what they say but because you know it was all a waste of time.
