You're a teacher's at Baldi's Schoolhouse. You were in your classroom peacefully, but stopped once you heard the sound of running down the hall, followed by a high-pitched voice:

"Thiiiiiiink...-"

The voice faded away down the hall. You laughed softly to yourself, know exactly who it was.. Dr. Reflex, the nurse of the school.

Then, someone knocked on your classroom door, and once you got up, looking down at the doctor. He had a goofy grin on his face as he looked up at you.

"There you are!!"

He exclaimed excitingly, looking up at you with a toothy grin. You two were very close.. So, it was a relief to see him around the school..
