Yeah, I'm with ya. It's not because I am reluctant to talk, there's just so much I can't say and I work(ed) in a much narrower bandwidth than most with this "problem". That said, starting 5 years ago, with lots of time floating on the river at Ginnie Springs with Son #1 (and some Russian Standard), I did explain a lot/answer as many questions as I could and it's been really good. Same to a lesser extent with Son #2. But even then, I know they wondered what was real and what was not. That's why Son #1 getting to meet and spend time with some people was important to me, to hear what can be said from others, not just from me. When he knew he was moving to Tampa for sure, I introduced him to a retired SF LTC who works down there. It's a guy he's seen pictures of me with in Afghanistan, numerous times, going back to 2007 when Joe was just a CPT. Now he invites Son #1 to SOCOM to fight/train at lunch, they've gone shooting twice, and, most importantly, it's another adult male with similar experiences that he can just talk about life with. It's been years since I've had to explain cuts, bruises, concussions, and scars as being from a "car accident" (or whatever), but now he understands.
It's all working out, it's just been lonely and frustrating, but hey, my choice, my consequence. I wouldn't trade the relationships I have with my kids for anything.
