Friends, great thread!!
I don't know what i would say to Ennis - who am I anyway? A stranger nobody listens to. I WISHED Jack had told him that line from "Love that will never grow old":
...
Lean on me, let our hearts beat in time,
Feel strength from the hands that have held you so long....
This line always lets me cry because it's so true

Ennis, you will always have Jack - feel strength from that, you are not alone.
