Let me share a story that happened to me during the exams today. I had ants crawling all over me for no reason. Really. I was doing my physics paper II halfway when i realised that i had ants all over my shirt. I furiously swiped them off but then they kept appearing on my desk and shirt. I looked down n saw like the whole bunch of them scrambling all over the floor. I guess they were falling down from the rooftop eh. Disgusting.
