I love you x

If I could catch a rainbow I would do it just for you
And share with you its beauty
On the days you're feeling blue.
If I could build a mountain
You could call your own
A place to find serenity
A place to be alone.
If I could take your troubles
I would throw them in the sea
But all these things I'm finding... Are impossible for me.
I cannot build a mountain
Or catch a rainbow fair
But let me be what i know best
That Girl Who Is Always There.
