The details from The Grasshopper and the Bell Cricket that allow the reader to infer that the narrator is an observer and outsider is D: Wide-eyed, I loitered near them.
Explanation:
In this line, there are two key words that describe the speaker as an observer and an outsider: wide-eyed and loitered. By saying that someone is a wide-eyed, we are describing someone that is a retailer, someone who likes to carefully study the surroundings, an observer. And the word loitered describe someone that is not in the center of the scene, but near. Someone that is observing where the action happens, but is wondering if that is what he/she wants or prefers to stay away. He/she is an outsider.
