toilet

that was my last exam in my high school. still remembered that that was the last paper of mathematics, and there was running out of time yet i felt stomach pain! i had no choice but asking permission to go to washroom. that time, my classroom was located at the highest floor in the entire school, and the washroom is on the ground floor. stomach was painfully and i need to run down to the washroom to release my painfulness!

after my satisfaction....i rushed back to my classroom and continue my last paper! that was so close to finish it...............
