Ooh-oo child, things are gonna get easier.
Ooh-oo child, things'll get brighter.
Ooh-oo child, things are gonna get easier.
Ooh-oo child, things'll get brighter

Some day, yeah, we'll get it together and we'll get it all done.
Some day when your head is much lighter
Some day, yeah, we'll walk in the rays of a beautiful sun.
Some day when the world is much brighter...

("Ooh Child" - written by Stan Vincent, sung by many)

I was a little unhappy earlier, and this song started playing in my head. I don't even know the song all that well so I'm not sure where it came from, but I found it strangely comforting.
