Yes, I forgot to add on just now.
I went home with phyllis ytd(same route) and we talked all along.
When we reached our station, she told me that she dare not talk to me for the past few years as she thinks that I am rather "dao", as I don't really smile.
I replied her that it was actually I don't really like to smile or interact with ppl that I am not really close to. She also agrees with me that I am different in class and outside class.
It's a fact.
You can see me pulling a long face in school, not in class.
I don't really like to entertain ppl sometimes by smiling if I don't like to.
I heard that it is true that many ppl in the school think that I am "dao".
I just want to be myself.
