However, there are a few instances that could be interpreted as metaphors:
* "My stomach was doing flips like a gymnast on a trampoline." This describes the feeling of nervousness and anxiety Greg experiences in a way that goes beyond a literal description.
* "My mom was like a one-woman wrecking crew." This compares Greg's mother's cleaning habits to a destructive force, emphasizing her intensity and thoroughness.
* "My dad was like a dog chasing its tail." This compares Greg's father's attempts to build a snow fort to a pointless, repetitive activity, highlighting his lack of success.
These examples, while not traditional metaphors, use figurative language to express feelings or situations in a more impactful way. Greg's simple style of writing makes it challenging to find clear-cut metaphors, but these subtle instances reveal the power of his language to convey complex emotions and experiences.
