Rain smells good because of a special smell called petrichor. When rain hits dry soil, it makes tiny bits of dirt and plants release a nice scent that people love. Some people feel happy when they smell this because their brain remembers good times from the past.
Examples
- A child runs outside after a summer storm and feels excited because the air smells like their favorite playground.
- An old man takes a deep breath in the garden during a spring rain and smiles, remembering his childhood.
- A student studying for exams feels calmer when the smell of rain fills the classroom.
