The writer is reminiscing about a time when they were studying linguistics in school, and the
lecture halls had their own cluster of seats. They also mention encountering squirrels on campus
that followed them into classes. There was an odd mix between excited shrieking from students who
didn't want to miss out or terrified screaming as if it knew something bad would happen soon.
Finally reaching a class late due to being chased by the same squirrel, which kept walking in with
him until they finally enter and find themselves mixed up together inside one of those lecture halls
that had its own set of rules for them both - no talking during lectures unless permission was
granted first!
