He overestimated his worth. He is just an employee receiving a salary from his employee. How rich can he be? I know of a few towkays living HDB who individual wealth can easily drowned him. He is nothing when compared with an oversea scholar from a neighbourhood school. Only ACS nerds absolutely look at primary school credentials.
He underestimated us, he delusionally believes that we don't have our own life abd everyone here must be very jealous of him because he studied in anglo-chinese primary school.
He has shown himself to be extremely snoobbish. In comparison, Ng Eng Heng is so humble, every day hunts hawker centre food after he retired.
You just have to stand up to him.
