So apropos of nothing, a gentleman came up to me and said "I just got back from Afghanistan." I retired from the military this year. I've got a pretty good sense of who has been and done and who has not. This guy did not have the vibe of a GI. He had the vibe of a pudgy dweeb who watched a war movie once and played make believe.
I asked him a few questions about his service in Afghanistan and he couldn't give respectable answers. So I started to turn away from him before I got annoyed. He then told some ridiculous story about putting a dismembered head into his lieutenant's helmet while the lieutenant slept.
I turned back around and he had this stupid smirk on his face. I said words to the effect that he had committed a war crime (depends on the source of the head, but it's not like he knew the difference). I was annoyed and it showed.
Pudgy dweeb changed the subject very quickly and soon left me lock jawed and trying to stare a hole in his back.
I see the guy fairly regularly. We don't talk.
He was pretending to be a National Guardsman. I have considered learning his name and reporting him to the NGB. For the time being I have decided not to hunt him and humiliate him. This is the new mature me.
But schmucko is hanging by a thread.
