We're at the movie theater and the preview for "2012" comes on ...
G (horrified whisper): The world is going to end in 2012?!
Me: No, that's all a bunch of baloney. No one knows when the world is going to end. Probably not for millions of years, though.
G: Oh. Okay! *cheerfully sits back to watch the rest of the previews*
Boy, do I wish I were still young enough to accept reassurance that completely. Not that I ever really did -- when I was about G's age or a bit older, I used to make my dad sit on the edge of my bed after lights-out and tell me all the reasons why the Soviets wouldn't bomb us. Imagine me lying there in my pajamas, saying "Okay, now explain the mutual assured destruction doctrine again," and you will know exactly what I was like as a child. No wonder I didn't fit in with the other kids in fifth grade!
