High school in the US spans four formative years that include memorable movies and TV shows, shared experiences like lunch tables and summer camp, and milestones like prom. It is a time when common idioms become familiar, such as "blowing a fuse" when angry, "dear john letters" ending relationships, "biting the dust" when something fails, and skepticism of change through sayings like a leopard can't change its spots.
