I do not know what is more of a concern, a VET. that speaks of their feelings or one who hides them from the world.
On one hand venting is great for those that have undergone a horrid experience. Naturally that can cause problems when a great uncle comes to call and repeats his experiences in WW2 on a pacific island fighting the Japanese for the 60th. time.
On the other hand family members or neighbors that never recount their military days, seldom smile or laugh---these people scare me.
This man should get his education and if he still after getting a degree wants to go into some kind of service for the Foreign Legion or as a paid Mercenary, God keep him safe.
From what I hear male RN'S. from Canada spend a few years overseas then come to the USA and work in Trauma in the hospitals---- My daughter had a male night Nurse that told me all about his adventures a few years ago when she was in ICU at the hospital.
There are ways to turn about horrific experiences into a life of constructive and worth while work.
