Lecturer must be strict?

my english lecturer is the kindest and the most caring lecturer.
she never scold us as she told us she is under probation.
However, those rascals in my class never know that it is tough being a lecturer.
They just keep on chat and chat although the lecturer shouted quiet at least 10 times.
Today is a considered bad day.
As usual, we went into class.
kim went to pass up the late assignment and teacher said that he was late and should get 0
As classmates, we should at least help him to gain a chance.. but wtf... those idiotic nerds.. keep on shouting yes~ 0 mark 0 mark~ yeah yeah~ u getting 0 mark
wtf lar...
kim defend by saying that someone told him he can pass up on wednesday
and again wtf those nerds shout excuse lar~ give him -0 mark
fuck lar....

kim was so fucked up that he came back and sit down wit a black face ... surely i also shows a black face..
and those nerds never knew what is friendship and respect for sure...

When lecturer start teaching.. todays topic is argumentative essay...
wao.. those nerds start to make noise and act smart.. keeps on giving pointless ideas and also annoying and nerditive ideas that the lecturer got so annoyed but she continue teaches.. i shout at the back i hate this class and the lecturer also agreed.. omg... wuhu~
hehe

then when kim was reading... those nerds were chatting and i shout
why the hell u guys never know how to respect friends..
==
they turn to me and say i was crying
wtf.....

later then the lecturer finish the lectuere and those nerds saw on the computer and saw a word file written the topic police brutality
the lecturer think for awhile and those nerds keeps on asking to open the file
under mass annoyance,, the lecturer open the file and start reading the article..
the article was about some police officers beating the prisoners and killing them...
and there is a sentence saying all 5 victims are not whites...
And here come the nerds acting smart and shouting means that they are black lar??
come on lar.. think b4 u speak lar
there is 1 negro in our class lar...

later then the lecturer gives us two topic to have an argument or we can call it as debate.
I and my "gang" chose the tough side while without assumptions.. those nerds chose the easy side.
they had at least 12 people and on the opposition side which is us.. only 6 ppl...
in 3 minute we already think out all the points that we nit.. while they are still discussing and still asking for more time... zzz.....

however... their points are really meaningless and non realistic..
easily we won the two topics.. =.=

I also respect the lecturer as she says that both team gives out good ideas, please goback to have a research inorder to get out with more points and maybe friday we will continue.
Both teams did well.
then kim keep asking whose points are more relevant or better.
the lecturer says that anything has pros and cons
kim asked again
and the lecturer say u go backdo the research then u will know
kim asked again and say based on todays performance,,
finally the lecturer says.. ur side wins.. haha~~ and the lecturer quickly says that what happens in class ends in class
dun argue outside the class or becomes enemy ..
lolz......
fucking nerdie classmates ...
