Respect.

Many people said that in college life you should be friendly and respect your lecturers because they'll give you good grade. But is that the only reason for you to respect them? No.

My girlfriend once got upset when her students (while intern) call her shorty and keep asking why she looks so small and tiny than their senior standard six primary school. At first, she ignored because she got that often. But eventually she just get bored. Then, she told them;

"eventhough i am smaller and shorter than you, doesnt mean you have the power to talk to me like that. Yep you are taller but your knowledge and respect to other people is lower and shorter than me. By that, you are nothing. You wont get anything (study) if you disrespect your teachers and olders."

And then, they sorry.

So eventhough the are younger than you, your junior perhaps, you should respect and be polite. When you do the beautiful things, people does the same thing. Come on guys, spread the love. Be respect.
