One simple qn I would ask her:
ARE YOU A VIRGIN?
I didn't know Hwa Chong very socially conscious that they force themselves to take the train.
Who let the dogs out? Guess the race.
Man...this I gotta try, to psychoanalyse her:
1. A Malay guy dumped her badly, thus paraphrased "I will never mix/hangout with you guys". Unmarried. And she masturbates a lot (don't ask how I know).
2. Multiple personality disorder, triggered in the train. Otherwise this behaviour at a workplace will never be tolerated and she will not last at any organisation. She is dressed to go to work.
3. Schizophrenia. She thinks she hears people talking about her and thus her response.
