Writing dialogue can be a lot of fun but it can also be tricky. Dialogue is not the same as conversation. It is not question/answer format.
Dialogue should lead to questions. It should entice the reader to turn the page. It should move the plot forward.
I've never heard dialogue called oblique before chapter eleven in Stein on Writing. According to Stein, this type of dialogue is indirect.
His example of oblique dialogue:
SHE: Hi, how are you?
HE: Oh, I didn't see you.
The man doesn't answer the question. He circles around it and says something else. That's oblique.
Have you ever heard of oblique dialogue? Or maybe you've heard it called indirect? For an exercise, here's some dialogue. Can you turn it into something oblique?
HE: Heard you had a party last night.
