I too would like to thank him for his service. Here are great big HUGGGGGGGGGGGs for him from me.
I understand how you feel about having him safely home. It's like your heart and lungs are restricted the whole time he is in harm's way and you can't breathe all the way freely untill he is home safely again.
My oldest son is a helicopter pilot/instructor for the National Guard and my other son was over in Desert Storm. As a mother, we always have that tension in us for their safety.
So happy you have your son home in the States again!!
