If You Still Have A Mother Comments

I have found what I believe to be the opening lines of this poem written in an autograph book by a German POW held in Scotland in 1946. He wrote this to the woman who befriended him because her son was serving overseas at the same time: Wenn du noch eine Mutter hast Dann danke Gott and sei zufrieden Denn nicht jedem auf dieser Welt Ist dieses hohe Glueck beschieden What do you think?
