I have lived over three years in the US, and I'll always have "a thing" for that country. My first son is born there, I have wonderful friends there, and I have tons of reasons why I should go and live there.
Last year, when we lived there again for 6 months, my two eldest children went to American public schools, and they would start every single day with holding their hand over their heart, while saying these words:
I Pledge Allegiance to the flag of the United States of America
and to the Republic for which it stands,
one Nation under God,
with liberty and justice for all.
I think it is beautiful. And, today, when I attended an American church service here in my local church, I had a hard time holding back my tears. There were Americans there, descendants of emigrants who, with broken hearts, left their families and friends, in hope of a better future. I heard stories of grandparents who never stopped talking about Norway, but never ever talked about the actual leaving... That was just too painful. Today, their grandchildren and great-grandchildren are Americans, but they carry with them a piece of another country, as do most Americans. This melancholy is maybe what makes USA special.
