Use of “that” in a sentence
What are some of the rules surrounding the word "that" and its inclusion or omission in a sentence? For example, "My boss mentioned that you needed help," vs. "My boss mentioned you needed help." Is either form more correct?
Sorry if this seems rudimentary, but I've always felt a little self-conscious about my own usage of this word due to some fuzzy but persistent high school English class memories.
