David,  I am first born generation on my fathers side and I do feel it was sheer good fortune of birth I am an American, but no I don't believe most Americans that happen to be just born here do nothing and take our citizenship for granted! To many of our men and women serve our country daily at great risk to themselves for our fellow citizens and our country! Americans every day do service to our country and their fellow citizens and think nothing of it, other then it's the right thing to do! We are so grateful to this country and what it means to be an American!
I'm sure if you phased your comment different I would have totally agreed with you, but to many that were just born here do wonderful things on a daily bases and don't take our citizenship for granted!
I'm glad you stood with your friend for this great opportunity and chance of a life time.
