The Postman Blooming Towards the Street Lamp

The old postman has been wearing a green uniform for thirty years. When delivering letters, he always adds an extra sentence - "The flowers are blooming" and "Come on, kids." The people in the town smiled and nodded, like the sunshine they were used to. On the day he retired, the mailboxes on every street were filled with letters. On the envelopes across the town, there was the same sentence: "Your words are the brightest light on this street." Only then did he realize that he had sent more than just letters in thirty years.
