This is very serious, and I guess this topic should move further
out of the forum (someone write to Straits Times please).
On another mark, I saw another kid (age 14-15) talking to himself
at Takashimaya S.C. I do feel very sad when these people appear but
it can't be helped, all kinds of people exist in this
society.
I would strongly encourage you to report this case to the police
and take appropriate actions. These people definitely do not belong
to this society.
