It's actually quite rude when u see a person u know and nv acknowlegde the party .. but praying in your heart that the other party did not see u ...

Yupz ...Although i do agree with what linlin had said the person is not oblige to come forward and say " Hi" to you ..etc

But i'm sure everyone was in the same kind of situation before but mostly if we avoid the other party was becuase those are not frens but only acquaintance else is that they pissed you off right in the face...

Conclusion !!

tsk tsk u r a rudie boi ~

you know who u r . . . keke :P
