catch the rainbow [英小诗:if,i,could,catch,a,rainbow]

　　if i could catch a rainbow

　　i would do it just for you

　　and share with its beauty

　　on the days you're feeling blue.

　　if i could build a mountain

　　you could call your very own

　　a place to find serenity

　　a place to be alone.

　　if i could take your troubles

　　i would toss them into 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

　　a friend that's always there.
