Double negative in sentence "一人くらいは来てくれるんじゃないかな..."


I was wondering about the translation of this sentence:
(一人くらいは来てくれるんじゃないかな...) What I see is a double negative and a question. Does
someone know if the double negative and question are used to _save face_ , in
a sense, from the speaker, or am I missing something really obvious...

来てくれるん - first negative. じゃない - second negative.




**In** **general** I think it's correct to say double negative and question
are used to save face but I'm not sure if this sentence is double negative.

The expression 来てくれるん is not a negative sentence and also the expression
`～じゃない？` does use the negative form but is not really a negative sentence
either and is more like a question.

For example, something similar in English may be

> Isn't it cold?

Japanese translation would be

> 寒｛さむ｝くない？

The expression `～んじゃない？` is used to say something with some assumptions and
also kind of asking for agreement from the listener just like the example
above.

Some examples are:

> 今日は雨がふるんじゃない？

(You see dark clouds) Don't you think it's going to rain?

> A: あ！財布｛さいふ｝がない！
>
> B: レストランに 忘れたんじゃない？

(You saw your friend use her/his wallet at the restaurant) Maybe you left it
at the restaurant?

`～かな...` is used to make it not sound like pushy when stating your opinion. I
think it's because it sounds like you are stating your opinion as if you are
asking it to yourself or talking to yourself. It's like `hmm I think`.
