I was busy making plans Like a castle of sand Never expecting the tide You were waiting by the shore Like you'd done so before Ready to help me to stand It took years for me to see it Even longer to believe it Dreams and castles come and go And still your love is The only constant thing I know Life is hard to understand But you're holding my hand And that's all I need to get by The rest will fall back into place Like the smile on your face And my heart will heal in time It took years for me to see it Even longer to believe it Many feelings come and go And still your love is The only constant thing I know And it took years for me to see it You keep me sane you keep me breathing Life is changing as we go And the one thing that I know Is I'm not scared of growing old As long as you're The only constant thing I love
