Sad Rain

In an ordinary small village, there was a little boy who always looked silly. When the little boy was in the third grade of elementary school, he couldn't tell the difference between an elm tree and a locust tree, a butterfly and a bee, a caterpillar and an ant, and a dandelion and a morning glory. The classmates in the class always laughed at him, laughing at him for not knowing what 5 plus 8 equals or how to write his own name? His classmates gave him a nickname: stupid kid.
