I don't know if you child was a returning war veteran, but know this..
I knew more guys who died shortly after leaving the service (suicide or drug overdoses, which I suspected were really suicides) than I knew guys who actually died in Nam.
And here I'm not talking about my former patients, but guys from my town that I went to HS with.
They came back, broken, indifferent to life, angry, confused, and now all used up, abandoned by the military.
Nobody I knew who was in the field, who actually slogged through the crap in Vietnam, I mean (many were there, but in sweet safe billets, understand, they were fine) seemed to me to be better man for having done so.
Combat vets oten have a difficult time fitting back in to the civilan world.
I knew quite a few guys who returned to the service, even so they could return to combat in Vietnam, because of that change in world view that they all seemed to undergo.
