Our company has a new strategic initiative to increase market penetration, maximize brand loyalty, and enhance intangible assets. In pursuit of these objectives, we've started a new project for which we require seven red lines. I understand your company can help us in this matter.

Yes, of course. Anderson here is our expert in all matters related to drawing red lines. We've brought him along today to share his professional opinion.

Nice to meet you! Well, you all know me. This is Justine, our company's design specialist.

We need you to draw seven red lines, all of them strictly perpendicular, some with green ink and some with transparent. Can you do that?

No, I'm afraid...

Let's not rush into any hasty answers, Anderson! The task has been set and needs to be carried out. At the end of the day, you are an expert.

The term "red line" implies the color of the line to be red. To draw a red line with green ink is, well if it's not exactly impossible, it's pretty close to being impossible.

What does that even mean? Impossible?

I mean, it is possible that there are some people, say, suffering from color blindness, for whom the color of the lines doesn't really make a difference. But I'm quite sure that the target audience of your project doesn't consist solely of such people.

So in principle this is possible.

I'll simplify. A line as such can be drawn with absolutely any ink, but if you want to get a red line, you need to use red ink.

What if we draw them with blue ink?

It still won't work. If you use blue ink, you will get blue lines. And what exactly did you mean when you talked about the transparent ink?

How to better explain?

I'm sure you know what "transparent" means?

Yes, I do.

And what a "red line" means, I hope I don't need to explain to you?

Of course not.

Well, you need to draw red lines with transparent ink.

Could you describe what you imagine the end result would look like?

Come on, Anderson! What have we got here, kindergarten?

No, I'm trying to get the...

Let's not waste our time with these unproductive quarrels. The task has been set; the task is plain and clear. Now, if you have any specific questions, then go ahead!

You're the expert here!

Alright, let's leave aside the color for the moment. You had something there also relating to perpendicularity?

Seven lines, all strictly perpendicular.

To what?

To everything, amongst themselves. I assumed you know what perpendicular lines are like!

Of course he does. He's an expert!

Two lines can be perpendicular. All seven can't be simultaneously perpendicular to each other.

I'll show you. This is a line, right?

Yes.

And another one. Is it perpendicular to the first line?

Well...

Yes, it is perpendicular.

Exactly!

Wait, wait, I'm not done. And a third one, is it perpendicular to the first line? Yes, it is! But it doesn't cross the second line. They're both parallel. Not perpendicular!

I suppose so.

There it is. Two lines can be perpendicular...

Can I have the pen? How about this?

This is a triangle. It's definitely not perpendicular lines, and there are three, not seven.

Why are they blue?

Indeed, wanted to ask that myself.

I have a blue pen with me. This was just a demonstration...

That's the problem. Your lines are blue. Draw them with red ink!

It won't solve the problem.

But how do you know before you've tried? Let's draw them with red ink and then let's see.

I don't have a red pen with me, but I'm completely certain that with red ink the result will still be the same.

Didn't you tell us earlier that you can only draw red lines with red ink? In fact, yes, I've written that down here! And now you want to draw them with blue ink. Do you want us to call these red lines?

I think I understand. You're not talking about the color now, right? You're talking about that, what do you call it? Per-pern-dick...

Perpendicularity, yes!

That's it! Now you've confused everyone. So what exactly is stopping us from doing this?

Geometry.

Just ignore it!

We have a task. Seven red lines. It's not twenty; it's just seven. Anderson, I understand you're a specialist of a narrow field. You don't see the overall picture. But surely it's not a difficult task to draw some seven lines!

Exactly. Suggest a solution that any fool can criticize, no offence. But you're an expert. You should know better!

OK. Let me draw you two perfectly perpendicular red lines, and I will draw the rest with transparent ink. They'll be invisible, but I'll draw them.

Would this suit us? Yes, this will suit us.

Yes, but at least a couple with green ink. Oh, and I have another question, if I may. Can you draw one of the lines in the form of a kitten?

A what?

In the form of a kitten. Market research tells our users like cute animals. It'd be really great if...

No...

But... but why?

Look, I can of course draw you a cat. I'm no artist, but I can give it a try, but it won't be a line any more. It will be a cat. A line and a cat—these are two different things!

A kitten. Not a cat, but a kitten. The little, cute, cuddly. Cats, on the other hand...

It won't make a difference.

Anderson, at least hear her out! She hasn't even finished speaking, and you're already saying, "No!"

I got the idea, but it is impossible to draw a line in the form of a cat...ten.

What about a bird?

So, where did we stop? What are we doing?

Seven red lines, two with red ink, two with green ink and the rest with transparent. Did I understand correctly?

Yes.

Excellent! In which case that's everything, right?

I almost forgot, we also have a red balloon. Do you know if you could inflate it?

What do I have to do with balloons?

It's red.

Anderson, can you or can you not do this? It's a simple question.

As such, I can of course.

Excellent. Organize a business trip. We'll cover the expenses, go over to their location, inflate the balloon. Well, this is very productive, thank you all!

Can I ask one more question, please? When you inflate the balloon, could you do it in the form of a kitten?

Of course I can! I can do anything, I can do absolutely anything. I'm an expert!
