The Department of the Navy sent Super Sub Cindy a thank you note for a recent article. It read in part: "On behalf of the United States Navy, thank you for your personal involvement in making Spokane Navy Week a great success, and for making the visiting sailors fee so welcome ... With you and your organization's help, we were able to show Americans throughout the Spokane area, the tremendous investment they have in their Navy."

Question: When did you last write or receive a "thank you" note?
