The best sounds

I wish I could bottle up this sound.  Right now the neighbor's daughter is playing with our kids in the backyard.  

Nothing beats the sound of kids playing happily together in the fresh air and sunshine.  There are no weird digital sounds, animated frenzy music, or [interruptions] ... wait, nevermind.  They're done, hungry, bored, whining, and badgering again.  But I got a blissful nap.
