You mean, she's really always like that?
She never smiles to people in greeting? Never?
She's really the quiet, introverted type like you said? Sure or not...?
Surely, to just give a small smile when you pass by people, it's not that hard is it?
It is just manners right? Instead of staring hostilely like an idiot when people smiles at you in greeting, why not try smiling back?
OH! You mean she really doesn't smile at strangers? But...we're not strangers what, we see each other everyday!
Seriously lo...it's just manners to smile when people smile at you right?!
OH! I get it!
She's just plain RUDE then.
