My action was not good enough today.

Today i had a talk with Mr. Cheng, my advisor. We talked about my research, my dissertation and Mr. Ren. He asked me whether i  admire Mr. Ren now. I thought that Mr. Ren might talk about me by telephone. In my view, do what i do.

 But i found i made some mistakes when i talked with Mr. Cheng. I should be more modest and make modest remarks in the future.

Another, I also made a mistake just now when i talked with LU. I should say whether you want to leave school now? It might be better.

And I should change myself and keep my mouse. I should not say anything to others, even though it is about joke. Because it may be a spear which may tick me.
I don't want to hurt anybody at any time. So, i choose not to say anything when somebody do or say something to me. I find whether my attutide give them a wrong impression. I don't know i should talk back to protect my poor dignity when they do that again. I don't want to show my aggressive in front of them.
