How to Keep a Secret
The final scene of every season of Lost was so hush-hush, we talked about it in code even on set. (We called it "the bagel" the first year, a variety of bread products after that.) I wanted to spill the news so badly, but I realized that spilling a secret is selfish. Our viewers wanted us to keep secrets from them, because it built their anticipation. Just like if I buy a pair of earrings for my wife for Christmas when it's not even Thanksgiving yet and I'm dying to give them to her, it helps to remember that she'll be grateful if I wait. Most secrets have to be kept only for a finite period of time, and when the beans are finally spilled, you'll be glad it wasn't you who spilled them.
