What does the speaker talk about in "Visiting My Native Country with My American-Born Husband"?

The speaker says that she has been changed by the
experience of visiting her native country because she recognizes the continuity of her
life in her new environment. In the many years before returning, she had taken up an
entirely new life, and realizes that, in effect, she has had two lives, or two separated
parts of one life. Even though she has virtually forgotten the first part, it is still
there, within her, as she sings a song she had not realized was a part of her that still
existed. The song symbolizes the virtually forgotten part of her that will always be
there even though it may rise to her consciousness only subliminally. Her husband, on
the other hand, has not changed because he is simply a visitor in her native country,
and his visit cannot occasion any deeply rooted memories.
