Lucy never came to the cooler, but I knew her better than that. After being her form tutor for so long, I knew her better than any other member of staff. She'd run rings around supplies and new teachers. If she had been sent to the cooler, she probably wouldn't have gone, and instead had been hiding.
When my turn on cooler duty was over, I searched the school. I couldn't find Lucy. She wasn't in her usual hiding spots. Lucy had been in class all along. Her usual disruption had ceased to exist that day.
I was becoming increasingly concerned about Lucy. Her change in behaviour was too drastic for me to ignore. I continued to monitor her behaviour for a few more days, making sure that I asked her if everything was okay everyday. I had no idea what was causing her strange behaviour, but I wanted to find out.
