john was a grumpy old man who never smiled. he was annoyed by the slightest disruption and could wear out even the most enthusiastic of neighbors. but he was also deeply curious, and he would sometimes gather the neighborhood children around him and tell stories about his adventures. his friends soon realized that despite his grumpiness, john's sense of humor was as sharp as a whip, often leaving them in fits of laughter.
