You got a new device, which behaves differently when you use it and when Rani uses it.

And now you're going to test how it behaves when more people try it.

You already got an idea.
You're male, she's female.
It behaved differently on both of you.
So it must be a gender detector.

A slightly complicated gender detector, but it might work like that.

Soon you reach your home, where your roommate Pipo is sitting at his computer.
You show him the device.

When he takes it, he seems pretty confused.

So?

You explain what he should do. He turns it on and presses the right button. The left light glows.
He repeats it a few times, and just like when you did it, a different light starts to glow each time.

Wow, my suspicion might be right.

What's so interesting about that?

If you're male, the other light is always turned on. If you are female, the same light is turned on.

Did you even check any girls already?

Of course.

Only Rani, I guess.

Yeah...

You should check more people. Maybe the neighbor girl would be a good start.

Hmm... good idea.

You hurry out and visit the neighbor girl. You almost never visit her but she's outside so it's not too weird.

You show it to her, so she can try it as well. She's still very young, so it takes a while until she understands it, but then it's the same result as for Rani.

That's enough! You immediately leave her and run back to Rani.
The neighbor girl stays behind and is confused now.

When you reach her repair shop, Rani isn't there anymore.
So you should enter her home instead.

You knock and Sali, a friend of her, opens.

Oh, it's you. Nice to see you!

You notice a weird smile on her face.

Sorry, I don't have time for you. I have to talk to Rani.

You get in and head towards the couch, where she's sitting.

I know, what it is. I tested it! It's a gender detector.

Can't you wait a bit. Don't you see I have a visitor. You can't expect me to be there for you, especially after you just ran away without telling me anything.

Rani seems very upset.

Oh...

A gender detector? That sounds interesting. I wonder if it can also detect my gender.

Since Sali is interested, Rani relaxes again.

Yeah, you should try it, too. One more check might be interesting.

Okay, how does it work.

You explain it to her. She giggles a lot.

Thanks, I get it!

When she tries it, something unexpected happens. The light above the other button glows.

Do it again. That's not what I expected.

She does it again and the other button glows again.

You aren't a real girl, are you?

Hey, I am. This device just doesn't work, I guess.

It doesn't? Maybe I was wrong. But maybe you're just keeping a secret from me. Let me have a look!

You grab her skirt in order to lift it up. But she doesn't let you.

Hey, stop it! The device just isn't a gender detector. Look!

She does it again a few times, but this time, the light above the same button always glows after she presses one.

Maybe it didn't work the first few times.

That wasn't nice. It's better if you leave now!

Uhm...

But I got an idea. Come back in a few hours and we'll find it out together.
And prepare to stay over night, just in case.

Yeah, sorry, I got carried away. I'll leave the device here for now.

You leave them alone and go back home, where you prepare for the evening and relax.
