Why are Singaporeans bilingual?

Why is my team comprised of a Cambodian guy and a PRC?

I finally realised how useful it is for me to be bilingual. Although my English is not really that fantastic but at least I guess most of the time I still can get my point across. But this time I really find it difficult to get my point across. I do not know whether is it me who's English is poor or is it that guy who just refused or cannot get my point? Then the other guy simply do not talk much, probably because his command of English is really poor. What can I do?

I am dead meat.
