The whole thing is finger-picked, but for the life of me, I can't figure out how. 
So here's the chords instead.

G                          Cadd9
This is a song I wrote last summer

            G              Cadd9
It's called... Water


           G               Cadd9
My hair is growing...

               G           Cadd9
growing all the time

         G                 Cadd9
Look how sensitive I am

                   D  C
cuz my voice is so fime
