This is an easy version of the song. You can experiment with the Em7 and G's and so on - 
this is just how I prefer it (to be honest I chose Em7 cause it's such an easy chord... 
yes it is nice to keep it simple sometimes).
If you prefer it another way, you are welcome to comment (other type of comments are 
also very welcome). Hope you enjoy!

Verse 2
Trees touch windows, say their hellos
Hear this house as it settles in
Worry slips away, it don't know your name
It don't know where to find us

Chours 2
Oh, as the light goes out
Thoughts turn to angles, all around us
Oh, as the night comes in
Dreams start their drifting, and we hear; a lullaby

End with
   G (320003@1)      D(let (xx0232@1)it ring)
...A lullaby
