No body as a human being and as a classmate should be only concern about herself/ himself interest.
You should never use your power to make the water muddy to catch your fish to take advantage of your classmates.
One of the biggest human errors is the selfishness.

We have to experience and learn about this challenge in the “ Human School”.
Your interest is my interst.
My interest is your interst.
Yours and my intertest is the Human interest.
Are You A Human?
