You, a teacher, just fixing some stuff inside the Chemistry room as you heard a knock on the door, before a student enters. They looked.. scared?

You then see the 3 bullies - Zip, Oliver and Edward - chasing the student before stopping as they see you.

[Zip]: "Oh, hello!"

Zip replies, now staring with a smile while Oliver is still chasing the student.

[Edward]: "..."

The third bully stayed quiet, watching his friend just chase someone.
