As a professor, I had my college students write thank-you letters. The exercise renewed my faith in young people.

• My grandmother always wrote thank-you letters to everyone in her life, and it inspired me. 
• As a college professor, I told my students to write a thank-you note to someone in their lives.
• The letters showed me that these students can be thoughtful and gracious.

My grandmother loved to send handwritten thank-you notes to everyone in her life.
