Wow, it's really amazing and shocking how people can change. It's not that I have not noticed that but that it was a total unexpected stunning encounter. I mean, I'm not invisible in front of you so why can't you just 打个招呼? Would saying a word of 'hello', 'hi' or whatever thing there is just to greet the other person kill you? It's not like we're both 陌生人 or something close or like that. I don't know the cause, but whatever the cause, I am feeling as if you 翻脸不认人. The feeling isn't good as such, I'm not going to disclose any names and I think someone has to take the initiative. Well, I consulted my tutor and she has a point, I could take the first step. I'm not pointing the blame at anyone but you know, arrggghhh...you get it don't you...
