We can never know the depth of pain and sorrow borne by the veterans of war.
'Thank you for your service' isn't enough, but what else can you say?
I found this photo comparison a while back, and although it's a Ukrainian soldier in the '40s, it illustrates what all war veterans must feel inside.
So many books & movies dwell on the scars they come back with and the ways they cope - or don't.
We owe them everything.
