Volitional: 見せましょう does not mean "let's have a look"?


> 部下：すみません、部長。この書類、見ていただけませんか。  
>  部長：  
>  1. ご覧になってください。  
>  2. 会議のあとならいいですよ。  
>  3. すぐに見せましょう。

Option 1 means, "Please have a look," using the honorific equivalents of
**見る** and **くれる**. This does not fit the context.

Option 2 is the given answer, to which I have no objection. However, I feel
that option 3 is also a viable choice, because **見せる** means **to show
something**. Saying **見せましょう** seems to me like the **部長** is allowing the
**部下** to show them the **書類**. I think this can be thus translated into
English: **Let's have a look right away then!**

If my understanding of this usage of the volitional form is correct, why is
option 3 not correct?

どうぞよろしくお願いいたします！




見せましょう would literally translate to "Let's show it (to someone else)!"

So it's not something that a boss would say to a subordinate who is trying to
ask them to look at something.

Possibly 見ましょう could be said by a boss at this point, though that seems a bit
too relaxed a response, it would translate to "Let's look (at it) (together).
However, since the subordinate is asking the boss to check something, in
theory because his authority is needed, or his input is what is valued, there
is little reason for him to suggest looking at it together with the
subordinate.
