Yes, I vaguely remember that during high school Sandra participated in an exchange program and was gone for one year to the United States attending a high school there and living with a U.S. family. When was that? Maybe 10th or 11th grade, although I am thinking probably 11th. She returned a year later to our high school and was maybe overheard to be saying something about her experience with her other family in the United States, although I cannot remember much. Where was that? Who were they? Why don't you ask her close friend Joan, who probably would know more about that, because I just have no idea.
