The mood in a story is the ambient or atmosphere the author creates to involve the readers and evoke feelings. Mood is created through the use of, for example:
Parallelism is a type of repetition. We repeat grammatical structures in a sentence or in a paragraph, usually with the purpose of emphasizing an idea or of improving readability.
Now, we must analyze how the parallelism in the excerpt affects the mood in the story. We can find parallelism here:
"I looked at the dog. He looked at me, tail waving. I looked at the lake. It looked back at me."
The use of subject + looked + complement helps the narrator create an eager mood. He is repeating actions taken and observed by him/her as a means to leave reader curious, eager to know what will happen next, just like the dog is eager to see the narrator jump.
