### Theory:

A metaphor is a figure of speech that makes an implicit, implied, or hidden comparison between two things that are unrelated, but which share some common characteristics. Metaphors are used to dramatize thoughts to emphasize and elevate the expression to a higher intensity.
Example:
1. Jack was fishing for compliments - In the real sense, Jack cannot be casting a lure to catch compliments from a river! It just means he was looking for compliments.
2. John was so hungry that he could eat a horse - In the real sense, it means he was extremely hungry, and he could eat a lot of food, but not a whole horse!
3. The sun is a golden ball - In the real sense, one cannot throw and play with the golden ball that the sun is!
Metaphors used in the poem "The Quarrel":
• "And somehow we fell out." line $$4$$ - Here, the fall out is not literally falling out and getting physically hurt but rather it is a difference of ideas between the siblings.
• "We can’t go on all night" line $$14$$ - Here, to go on  is not to go somewhere, it is a compound verb which means to continue.
