Karen,
Very well written. This really could have been horribly sad or maudlin -and you avoided that entirely. Instead portraying real emotion in such a genuine and gentle way.
And knowing who the story "really" is about gave me a huge lump in my throat.
As a military spouse for a number of years, I can only say that I know exactly how you feel, and if Superman isn't good for some wishful thinking, then I don't know who is! You put him to good use here.
Godspeed to your brother and nice writing, Karen.
