Curious case of missing papers

As mentioned previously, GP exam was on saturday. We were supposed to collect our history mock exam paper that very same day, but i forgot; i had already taken the bus near the MRT. Feeling a sense of urgency and guilt, i decided to go back to school and take the papers - for comments, which may help to improve my essay writing.

Went up to the locker and tried to find my paper. Missing. Ok. Might be with friends. Asked classmates, none had it. Ok. Started to panic.

Then this morning, received this message from the tutor:

"Dear all,

I am severely disappointed with the class.

a. I found Ziyi's paper ON the pigeonhole cabinets. The person who left it there has been extremely irresponsible as it could have simply be blown away by strong wind."

Extremely pissed off. How not wonderful.
