Human's heart is complicated...

I feel that human are very complicated beings. they look good at the outside but they may be rotten in the inside.. Rotten as in evil intention/ watnting to win etc...

E.g. My friend told me that there is once, she dont understand a certain subject, so she asked someone who is good at it.. That person deliberately taught her the opposite thing and of course, she failed it and that person is like top of the class.

So what do u all think? (I come back to post this after so long.. must give comment hor... hahaha)

Purposely teach wrong thing!? OMG... Evil!!!

That's worse than refusing to help sia.
