how can i write the sentence in english?

我同佢唔係好熟 Usually, we will have it interpreted as:
I am not familiar with him/her.
若然學你咁講: I don't have a close relationship with him.
我只會理解作: 你同佢係有關係嘅, 但並不太密切!



2008-08-21 12:57:59 補充：
要知用上 relationship 呢個字, 直指"關係". 表格上常以此字作血緣關係上之詮釋, 例如: father and son 又或 mother and daughter。.又或可作法律上之關係, 如 husband and wife

至於生意上, 亦有 business relationship 一形容詞, 即係有生意上之關係!

我=I, 同佢= WITH HIM/HER, 唔係= AM NOT, 好熟= VERY FAMILIAR

Therefore 我同佢唔係好熟 in English is written as:

I am not very familiar with him/her.
