We had an exchange student from Germany for six weeks and learned quickly that being a host family meant being a real family.
She arrived with a dental problem. She was in so much pain and tried to downplay it until it became obvious we needed to take her to a dentist immediately.
Luckily, our dentist is phenomenal and has a state-of-the-art office with the best equipment imaginable. He was so taken aback by the poor treatment her own dentist had given her prior to her trip to the states, he gave her a free root canal.
Her insurance covered everything but our dentist's good will and fair treatment made her trip more than just a fun visit to America. She fell in love with Americans and has since returned several times.
Our exchange student became more than just a visitor, she became family. This is how it goes when you open your door and heart to a student.
