I thought of another Veteran.
Gerry - a friend and former neighbor. He served in Vietnam and his life has never been the same. He was 19 when he was hit by a mortor (friendly fire). He suffered many many injuries, but the most obvious was permenate blindness. You can see on his arm and leg that the doctors did their best to put him back together, but there wasn't enough flesh left to make it look just right.
He doesn't let this ruin his life!! He enjoys his guide dog and gets out as much as possible. He met his wife at the VA hospital and they have two children together and I think four grandchildren. He can have quite the potty mouth, but you can't help but laugh. And he would serve his country all over again if he could.
