Something from Key & Peele I randomly thought of today

[Doom Metal Alchemist]

For whatever reason, it popped into my head when Key & Peele were setting up a sketch to the audience. I don't even remember what the sketch was, but the setup was pointing out how in movies involving the white house and government and stuff, they never say "goodbye" or anything when getting off the phone. They just abruptly stop talking and hang up. 

Today, I think I realized why this is. That happens in tense scenes in the movies, and I think if a character in such a tense scene would say, "Alright, I'll talk to you later. M-bye," it would take everyone in the audience right out of the moment and it would feel awkward and not the kind of tense they were going for. So, not only taking out the "goodbye" (what's the opposite of a greeting?) and just abruptly end the call, not only does it keep the tense feeling from the scene intact, but it might actually add even more tension just by nature of the call ending abruptly.
