Hard cargo lyrics

I work the long haul on the dockside Building boats is what I know Each one takes another year of my life And then I watch them go There are no lights around this harbour The tide has never been so low You teach them to walk and then you teach them to run And then you watch them go. You watch them go (Chorus) And it's a hard cargo to carry To see them slipping away And it's a hard cargo to carry To see them slipping away, slipping away Mary was the one who waited Even when the working was getting slow You think you know somebody inside out And then you watch them go. You watch them go (Repeat chorus) I believe that when you go You leave something behind I believe that out of sight Is never out of mind And then you watch them go, you watch them go... And it's hard cargo to carry To see them slipping away... Slipping away, slipping away
