Scene: A cozy balcony in São Paulo. The sun has just dipped below the horizon. The city glows in golden twilight. Carlos and Rafa sit on hammocks, sipping chilled guaraná.
Rafa:
(whistles a samba tune softly)
What a beautiful evening, huh?
Carlos:
(startled)
Rafa! Stop that! You’re whistling after sunset!
Rafa:
(grinning)
So what? I like that tune.
Carlos:
You’re going to invite bad spirits, cara! Haven’t you heard the saying? “Quem assobia depois do pôr do sol, chama espírito ruim.”
Rafa:
(laughs)
Carlos, we’ve been through this. Spirits don’t have a whistle-detection radar. It’s 2025, not the 1800s!
Carlos:
Mock all you want, but my grandma swore by it. She once told me that after she whistled at night as a girl, the next day the family chicken disappeared. Just vanished. Gone!
Rafa:
Maybe the chicken got eaten by a fox, not a phantom with a taste for poultry.
Carlos:
It wasn’t just the chicken! The next week, her cousin saw a shadowy figure behind the mango tree. No one whistled again for years.
Rafa:
(laughing)
You sure it wasn’t just your cousin seeing your uncle in a poncho?
Carlos:
You joke, but why risk it? Lots of people in the countryside still believe this. There’s gotta be a reason.
Rafa:
There is a reason—it’s cultural. In olden times, whistling at night could attract attention from wild animals or even thieves. So the elders made up a scary story to stop kids from wandering around. Practical, not paranormal.
Carlos:
Still sounds like spirits to me.
Rafa:
Okay, let’s say spirits are real. You think they’re hanging out, bored in the spirit realm, until someone whistles the first few notes of “Garota de Ipanema,” and then they go, “Ah, finally! Someone summoned us!”
Carlos:
You know how it works! Sound carries differently at night. Maybe it opens a door.
Rafa:
That’s poetic. But science says sound travels further in cooler air due to lower thermal turbulence. Still no ghost hotline triggered.
Carlos:
But what if the sound frequency messes with something spiritual? You can’t prove it doesn’t!
Rafa:
True, I can’t prove a negative. But I can say there’s zero empirical evidence. No controlled study has shown ghosts appear when someone whistles after dark. And you know scientists love proving weird stuff!
Carlos:
(grinning)
So what if I just… don’t want to be the case study that finally confirms it?
Rafa:
Fair point. But what if we’re letting fear of old tales limit our lives? I mean, what’s next? Not clipping your nails on Tuesdays?
Carlos:
(rubbing his chin)
Actually, my aunt says—
Rafa:
No. Don’t even start.
Carlos:
(laughs)
Okay, okay! But can you at least not whistle when you’re with me at night? Out of respect for my nervous system?
Rafa:
Fine. Deal. I’ll save my Grammy-winning whistling for daylight hours. But only if you promise not to blame me if your TV remote goes missing tomorrow.
Carlos:
Deal! But if I see a shadow by the mango tree tonight, I’m calling your rational butt first.
Rafa:
And I’ll bring a flashlight and a stack of peer-reviewed journals.
They both laugh as crickets chirp in the background and the city lights twinkle like stars.
