Silver Lining - a metaphor for optimism according to Wikipedia.
I never heard of this idiom until I watched the movie Silver Linings Playbook which made Jennifer Lawrence win the Oscar's Best Actress award. Of course, her fall on the stage because of the dress made her even more famous. It made a lot of people talk about her all the more. She's funny and "REAL". Some may say that she's a bit of a clumsy lady but I like her.
The movie starred two emotionally disturbed individuals. One has a bipolar disorder - Pat Solitano Jr. (Bradley Cooper) that after being released from the mental institution has become very focused and positive about winning his wife back. Then he met the widowed and depressed Tiffany Maxwell (Jennifer Lawrence) who made him realize that life sometimes don't go according to his plans. Amidst their differences and the problems that they both have on their own emotionally, that silver lining made it all possible for them to realize that they're meant for each other.
"This is what I believe to be true. You have to do everything you can. And if you stayed positive you had a shot at a silver lining." - my favorite line on the movie. :)
It's a different kind of romantic comedy. It's crazy but really fun to watch. Both Bradley and Jennifer did great on the characters they played. Here's the trailer:
Better watch the movie and have fun! :)
