Dialogue tags and I have a difficult relationship. Avoiding them in the manner you describe can break pacing. Yet, that endless stream of boring tags otherwise distracts. Avoiding tags and descriptions altogether in two-person dialogue assumes the reader doesn't get lost. I know I do.

It's all frustrating.

I avoid dialogue except when needed. I prefer to attempt to describe the essence of a dialogue, rather than to state it. Then again, there's the "show don't tell" rule, which this tactic threatens to violate. This usually means I mix the two. There's some talking, then a description of why characaters take the positions they do, and then do some dialogue of the resolution. 

With dialogue, often less is more. 

Thanks for this post. I am clearly not alone in my suffering.
