If you have children, you might occasionally lie in bed late at night with your eyes open, staring into the darkness, wondering what might become of them. What will they do? Where will they go? What will they dream about? What will they love?
You might also wonder if you’re doing a good job. Am I teaching them everything they need to know? Do they see my bad habits? Are they genetically disposed to follow in my footsteps? How do I know if they are truly happy? Maybe you’re simply hoping that they’ll go back to sleep, or that they won’t wake up, because you can’t handle one more night of ‘Dad, I need some water’ or ‘Turn the music back on’ at 3am.
