My son is an active duty sailor aboard a guided missile destroyer.

14. You have every right to be proud of your son.

And, no doubt, you raised him to think for himself and to distinguish between right and wrong.
I was in the Navy myself, on a Guided Missile Cruiser and on a small Destroyer. I did my job, made great friends, then got out (I sometimes had officers who were more interested in making a name for themselves than they were in safety and well-being of their crew).
I hope your son does well, and enjoys his time in the service.
By the way, as we get older we find that being a Veteran has a lot of benefits, especially health related! And home ownership, which is getting to be out of reach for MANY folks!
