done a good deed

Today i helped everybody in moral class to do something GOOD

The teacher (pn.khoo) asked a person's moral marks for last year.
She listen 67 to 57
so i correct her lo........
I said: " Puan khoo, it's 67 la............. U heard wrong again la (not 1st time)"
Some said i did the right thing
some clapped their hands
I feel like a hero............................................................................................................
and she very stupid lo,
agama said as ugama
Told her already pun tak nak correct.
Too old to change?
