Why do movies (and TV) sometimes have this weird dialogue pattern?

Here are some examples of this weird dialogue thing I’m talking about:Ex.1Person 1: “Do you miss it?”Person 2: “Huh?”Person 1: “The Ocean, California, do you miss it?”Ex.2Person 1: “It’s actually pretty cool.”Person 2: “What?”Person 1: “The fog, it’s kinda cool.”Ex.3Person 1: What happened?”Person 2: “What happened to what?”Person 1: “To us. What happened to us?”It’s this weird call/answer dialogue pattern where person 1 is weirdly vague about what they mean, person 2 asks them to clarify, and person 1 clarifies. I don’t know if it’s just me, but I have never heard this dialogue pattern in real life. Now that I’ve become aware of it I’m noticing it pop up everywhere in movies and TV and it’s bugging me.Is there are reason behind this kind of dialogue? Is it just to pad out runtime? Is this an actual normal way people talk that I just haven’t witnessed before?I need answers damnit, help please! via /r/movies https://ift.tt/2Vg2XOc
