Desperate Housewives, Season Four

Mary Alice Closing:
"There is nothing more decaptive than a smile. And no one knows this better than the people who hide behind them. Some flash their teeth as a polite warning to their enemies. Some put on beaming faces to keep their tears from falling. Others wear silly grins to mask their fear. But then there is that rare smile that is actually genuine. It's the smile of a person who knows his troubles will soon be over."
