Jenny Lewis

I think I have a hard time expressing myself in my relationships. I use songs to tell people how I'm feeling. If I can't say 'I love you,' I'll write a song about it and hope that the person figures it out.

If you think about evolution, sleep, at some time, was a dangerous undertaking. You lie down in your cave or shelter, and along comes a predator and has you for dinner. Many creatures do not sleep or sleep while standing so they can escape from dangerous situations.
