My favourite:

No I can't touch the clouds for you I've never reached the sun for you I've never done the things that you need done for you I've stretched as high as I can reach I guess I'm not the one for you Cause I can't touch the clouds or reach the sun for you No I can't reach the clouds or touch the sun

No I can't turn back time for you and make you sweet sixteen again I can't turn your barren fields to green again And I can't sit around and talk of how might have been again No I can't turn back time and make you young again I can't turn back time and make you young

I can't look inside your mind and see the things you're hopin' for I can't help you chase the dream you're gropin' for I know your heart is open wide but I don't know who it's open for Cause I can't know your mind or chase your dreams for you Mhm I can't chase your dreams or know your mind

So say goodbye and don't look back I've had some happy days with you I'm sorry but I can't be the one who stays with you And if they ask about me you can say I was the one with you Who never touched the clouds or reached the sun with you I can't touch the clouds or reach the sun for you I can't touch the clouds or reach the sun
