Will not think about that tomorrow

I feel alright now after going to the HKUST recruitment talk. And talking with Stanley is really motivating. He's such a high potential talent and should really run for MC.
Mr Chan told me not to think about that again tomorrow, so, that means I have to think as much as possible tonight. So I decide to write it down, express it all, finish, and not to think about it tomorrow.
I have never imagined anyone cursing my family in my face. And worse till, it's not that she does not know my father. My father even treats her some lunches and talk with her nicely. I just could not believe any reasonable person could say something like that.
My father is not in Hong Kong and I miss him. And somebody saying this to me is just purely unforgivable. I told myself, maybe she does not mean it, maybe I misheard it, maybe, maybe... But anyway, just like Mr Chan said, no matter what, it is not right for her to say something like that.
I don't know how to deal and work with a person who cursed my father. It's just impossible.
Both Mr Chan and my mum said now I know this person, I should note that down as a "learning point", and beware of her. I will.
