daylight savings

Tim reminded me today that tonight is daylight savings, and I rejoiced.  Esther asked me what it meant, and I explained that we get an extra hour of sleep!!  At first her face mirrored my excitement, but as she processed what I had said it fell ludicrously.  An extra hour of sleep?!  What's good about that?  Well, Esther...it's hard to explain, but you'll understand when you're a grown-up!  :-)
