Strange Woman
Looks like in her 50s.White hair,skinny,wears sleeveless and seems
to have something stuffed at her tummy to make her look pregnant.I
have seen her walk from one end to the other end a few times
liao.She looks a bit disorientated,can tell that she is a mental
case.
Strange Man

berms.sandals.The berm is pulled very up.He don't look like a
nutcase at all though he looks like your typical nerd.He likes to
take the escalator.He also walks from one end to the other.
