That's the thing. We who have served know what we're taking about. Those moments we shared with our brothers in arms that can never be explained to or understood by those who haven't "been there". It's cool because sometimes you're talking to a service member or former service member, and you get it . You know EXACTLY what they are trying to say, without them having to elaborate it. And other times, it alienates you. You try to explain it to High School friends and relatives and they look at you like no matter how much you explain what you're trying to say, they will never truely understand you. It's especially difficult to get through to your Family. Wife and kids. That's when it alienates you the most. Knowing your life will be spent with them, but there is a side of you they will never truely Know.
