An 11-year-old girl’s letter to her local mail carrier thanking him for his service evolved into a thoughtful message on mental health, especially during the coronavirus pandemic.

Emerson Weber, a fifth-grade student in Sioux Falls, South Dakota, has been known for years by family and friends for the thoughtful and frequent letters she sends, each wrapped in an envelope elaborately decorated with her own designs.

“I love being able to decorate the envelopes. It really shows my creative spirit,” Emerson told “Good Morning America.” “Writing letters you can share so much about your self, it’s like being there in person, and, I love receiving them, because you know that someone took the time in their day to write back to you.”

Emerson, who has her own address book and keeps track of stamps and envelopes, recently decided to write a letter to thank the person who makes sure her letters get where they need to go, her local mail carrier Doug.

“I’m Emerson. You may know me as the person that lives here that writes a lot of letters & decorated the envelopes,” Emerson wrote in the letter to Doug. “Well, I wanted to thank you for taking my letters and delivering them. You are very important to me. I make people happy with my letters, but you do too.”

“The reason you are very important in my life is because I don’t have a phone so how else am I supposed to stay in touch with my friends? You make it possible!” she wrote in the letter, which was shared on Twitter by her dad, Hugh Weber, founder of The Great Discontent, a online platform for creative professionals and content curators.
