Everybody can hear 'it'

Hi there! So, I had my second paper today; Chemistry. The exam starts at 2.15 pm., so we went there at about 1.45 pm.. I was pretty excited about finishing this paper because it will means that I have one last paper left next week. Yeah, I know. I am so lucky (considerably lucky) for having only 3 papers in this exam. 


Forget about that, here is the deal. I was pretty confident with my answers, until my stomach suddenly made an announcement at the hall;

I looked to the left, and turned to the right. I am pretty sure that nobody hears that, since everybody were so absorbed with their own problems. However, my stomach just won't give up in making itself get noticed;

I tried my very best to pretend as if nothing happened, and continued to answer my paper. However, I am pretty sure that somebody might have heard it, and will spread the news to the world soon after my exam has ended;

Okay, here is a trick question. Which one do you think I am?

The exam was supposed to end at 4.15 pm., but I ended mine by 3.30 pm.. I was TOO hungry, since I haven't ate anything since breakfast. I rushed home, in hope that nobody will remember my face or my stomach. Ha ha!

p/s: I've learnt that I need to eat before attending anything like this in order to save myself from dying because of embarrassment.
