"
And once they're gone, you'll never get that back
No more laughs, no more hugs
So hold on to the ones you love
Your soul is free, I love you, Anthony
He is saying that when someone passes away you can't tell them anything you can't tell them that interesting fact that has been in the back of your head for weeks. Once they're gone you can't say your last goodbye to them. Once someone is gone they are gone and you can't bring them back and I think this song expresses that in an inspirational way and an emotional way. This song gives me tears because I wasn't able to say goodbye to someone I love and it hurt me.
