I'm watching the clouds float above my house Things can never be that simple I dream of you and I, thinkin' we could fly Our castle in the sky has crumbled Letting go can be the hardest when you are filled with sorrow You don't know how heavy the heart is until your heart is hollow Ooh-ooh, ooh-ooh, ooh-ooh, ooh-ooh Ooh-ooh, ooh-ooh, ooh-ooh, ooh-ooh Dreams that we fulfilled, and all the worlds we built Are all I have to fill my memories Would have never guessed this weight that's on my chest Would heed me when you left me empty Letting go can be the hardest when you are filled with sorrow You don't know how heavy the heart is until your heart is hollow Ooh-ooh, ooh-ooh, ooh-ooh, ooh-ooh Ooh-ooh, ooh-ooh, ooh-ooh, ooh-ooh I'm watching the clouds float above my house Things can never be that simple
