never mind

It's my fault that i set too high target for them. I shouldnt expect they listen to me all the time and remember everything I taught.(I didnt do so) 

What I have to do is just my part and responsible to my job, my ex-colleague was right. He said, "Dont have to too care about them! You will feel easier to teach other students after you "tormented" by them!" Yeah, maybe. My EQ will be higher! good training!

btw, tomorrow is BERSIH 3.0. Just support them at home. Hope that everything will be fine! 

I got night mare because of those devils!
