When I was young enough I had no ideas of the reasons some one would join voluntarily. Or involuntarily. I thought "war" was dumb.
Now at 38 I have grown - I wish I could have joined the Marines to do Marine stuff. I understand now what soldiers have done and what I could do to save the weak and helpless. And I understand that that the life I give would be my only one...
I feel nervous about each and every one that serves my country. They are not my friends, but I wish they could be, so I could somehow give them something of my love for life that might keep them positive at the end.
