Awkward character conversations

I often think about what characters on TV shows or in movies talk about in the car on the way back from an awkward or traumatizing situation, because they only ever talk about what happened after they reach their destination. 

"So... you wanna stop and get a McFlurry?"

 "No Matthew, I do not want to stop and get a McFlurry. You just murdered 5 babies and a dog back there with a hatchet, and we now have to pay those gangsters 10 million dollars, which we don't have by the way, or they'll kill us!" 

"Well... we'll talk about that when we get back. So... are you absolutely sure you don't want a McFlurry?"

They talk about frozen treats, that's what!
