will i be great on my 1st year?

actually i wanna put video for my song last week that i wanna post.
well, forget it for awhile.
Now, i really disappoint for my class teacher cz she's too lazy=.=
never see teachers lazy before until im in a 1st year in secondary school(+bm teacher, they are all so lazy...)
next monday, i'm on a choir competition but my class teacher did not controlled their discipline when we were practice.
OMG!!!
T.T
gotta cry...
then i'm shouting to them and scolding them, and so they dislike me(hate me)
haiz~
what wrong wif me?
i'm not mean to make them hate me on my 1st year in secondary school...
but this seems not so easy...
well, i hope that our team(our class) can be in the grand finale competition team.
hope that they will listen and follow me until the end of the competition.

p/s: pay attention when we're performing, this is for all of the choir team members.

Thanks,
qarz^^
