Use of “that” in a sentence
Some times I find myself leaving out the 'that' that binds two parts of a sentence together, because it reads 'smoother'. Here's an example:
I'm at that point towards the end of a book, where you suddenly realize you're reading part two of a trilogy and too much of the plot is left for a satisfactory resolution.
I chose to not say '...suddenly realize that you're reading...'. Is this still correct? Is it merely a more informal tone? Bad style?
Side question: What am I actually talking about in grammatical terms? Binding two sentence clauses together with ’that'? What kind of word is 'that' here?
