Amzingly well done
I am going to try my best and explain my thoughts and vision for this song.
As you said your self "A sad true story" i see a couple losing a loved one or someone really close to them. As the song goes on the couple are getting older and so does their children grow up and the parents begin to share their knowledge and wisdom the loved that had passed on shared with them.
Well, took me some time to type all that (i know it's not much) but here you go!
Loved it ! 10/10 - 5/5
