Too bo liao, so browse around the forums.
stumbled across an old thread:
http://www.sgforums.com/?action=thread_display&thread_id=194450&page=0realised that that lady mentioned quite matches to the one i have seen ( not in that toilet lah! i cant enter femal toilet

)
have actually seen her boarding the mrt at somewhere amk station.
as i was on my way to the MS foodcourt, she was literally near me the entire trip

she sure stinks!! white white unshavelled hair, squatting in front of the mrt door with a portable radio switched on loud ( not a earphoned one, but a speaker one -_- )
did not see her again after im at MS level 2 tho' ( maybe she headed straight to that toilet?

)
juz bored

so juz +1
