When I am at tekong as a recruit we used to see one figure walking at the other side of our block at night.... Being recruits we all have very short hair but..... this figure has long hair!!!..... It started as a few making comments of a ghost and ended up with most of us believeing in it.... Then one fine day the truth was out..... the 'ghost' turn out to be a 'Ah Seng' who unwrap his turban....
... it is not mean to be a racist joke and I apologise if i have offended the Silkh communties...... it is just an illustration of a possible reasons.....
