I can manage all four of these thoughts in one head. I can usually avoid saying them all at the same time.
Fortunately...or unfortunately, I don't know which...I've yet to have this issue with any of our kids. However, we have sent two nephews overseas in the military due in some small part to my prior service. And my little brother is on his fourth combat tour. This time in the 'Stan. Yes, the reserves still deploy.
He and I have talked at length about enlisting/re-enlisting and the reasons why people remain in the service. I am simultaneously humbled, honored, and made jealous by his continued service to our country.
I have some combination of the above running through my head every time we talk.
