A few years ago, I read everything I could find by Henri Nouwen.

His writings were formative and very encouraging.  On one occasion, I read his book Gracias.  The book is actually a journal chronicling Nouwen’s time spent in Peru and Bolivia.  Near the end of the book, he writes:

The title of this journal summarizes what I found, learned, and heard.  The word that I kept hearing, wherever I went, was: Gracias!  It sounded like the refrain from a long ballad of events.  Gracias a usted, gracias a Dios, muchas gracias — thank you, thanks be to God, many thanks!  I saw thousands of poor and hungry children, I met many young men and women without money, a job, or a decent place to live.  I spent long hours with sick, elderly people, and I witnessed more misery and pain than ever before in my life.  But in the midst of it all, that word lifted me again and again to a new realm of seeing and hearing: Gracias!  Thanks!  (Henri Nouwen, Gracias!, p. 187)

Question:

When have you felt particularly moved by someone’s gratitude?  What made the situation particularly moving?
