I think Shadelayers was quite spot on about your "questions", coming from a research professor or professor doing research... whatever.
You then tried to bombard him/her in English, and with the big words that were used wrongly, thinking she would be intimidated. I guess you have picked the wrong guy.
Now that we are taking about international school here and some members go on things like English proficiency. Based on your English, being a professor in HK, it certainly reflected the pathetic English proficiency among the local students even though they manage to graduate from university and become a "professor"!
I am not saying my England is perrrrrrfect, just can't stand your ignorant.
