Should I listen to my professor?

I was embarassed by my professor in my Credit Transaction class this evening. We were discussing what is and the difference between the ordinary expenses and extraordinary expenses incurred by the parties to a contract of loan as part of their obligation. In my effort of trying to answer his question, he commented that I'd rather take up vulcanizing because in vulcanizing I do not have to think.

At first, while standing in front of him while he says all that hurting stuff, I would like to burst out my feeling and yell at him. Why do I have to enroll for a vulcanizing course if I already have a job which may be higher than what he gives to his secretary. But I have to show composure as a fine lady taking calmly the battle of proving myself to him. When I was done, I told my seatmate that I would mark this day in my diary and when time comes and I passed the bar examination, I will deliver my testimonial speech telling everyone that I am thankful I choose not to listen to the non-academic and personal opinions of my professors in law because if I did, I turned up to be a vulcanizer rather than a lawyer.

This is a challenge for me and a wake up call to bring the fire inside of me, wanting law again and not be discouraged by how the professors in my school handle their class. A part of me says that I should instead be thankful that there are people and professors like him. Even though they are so strict in class, they know their law and they know what they were saying unlike other professors who just discusses without determining whether their student truly understands them. These kind of people are the people you would thank for someday because at some point in your life, they turned you to a direction you wanted in the first place. After all, this is not the first time I got embarrased inside the classroom. There are many more battles that I have to face and strugglings I have to overcome. The battles during examination and recitation inside the class is just a reflection of what is store for me outside. I should really always be prepared. The battle to prove myself continues until the day I can't prove something anymore.

The answer to his question is that ordinary expenses are the necessary expenses which arises from the wear and tear of the thing loan while extraordinary expenses are the sudden or abrupt expenses incurred arising from the use of the thing loaned.
