Feelings about...the lack of dialogue or...the strange lack of dialogue?

I think we have all seen the posts "What was my character thinking?" and the like, where there is a lack of dialogue in the story.<br><br>This use of "show don't tell" is where a character might not say anything. And it is fine. I'm not talking about that...if I said that, I'd be hypocrite...because, as you may know...that is what I do on that Chambers post.<br><br>But I'm talking about the lack of inner dialogue or reaction on the part of the character...I'm not talking about the character being speechless or that the character didn't say anything...I'm talking about a lack of dialogue on the part of the character that is being written. Now, the question I've had has been..."Is it strange for an author to write about a character without any inner dialogue?"<br><br>Are characters supposed to always have...at least some kind of inner dialogue...or...should you leave some things to the reader's imagination?
