Growing up and maturing "...whilst holding hands and we'll hold on" --> holding on to parents hand as a metaphor for trying to cling to their childhood, scared to grow up "Cross the road and say goodbye, there wasn't a dry eye" --> Crossing the road to the "other side" ie grown up life, parents "crying" because they don't like seeing their children all grown up, while the kids are crying because they still want to be children, and are now scared of being independent">
This song is clearly about growing up, but not wanting to and thus reminiscing about childhood
"and the days when we learnt screaming are we there yet doesnt get you any faster" --> Growing up and maturing
"...whilst holding hands and we'll hold on" --> holding on to parents hand as a metaphor for trying to cling to their childhood, scared to grow up
"Cross the road and say goodbye, there wasn't a dry eye" --> Crossing the road to the "other side" ie grown up life, parents "crying" because they don't like seeing their children all grown up, while the kids are crying because they still want to be children, and are now scared of being independent
