No, lol, I'm just trying to get you in trouble. You're telling me there's no one right answer? Like how long is a piece of string?
Here's a riddle for you:
She has tasteful friends
And tasteless enemies.
Tears are often shed on her behalf,
Yet never has she broken a heart.
You're telling me there's no one right answer? Like how long is a piece of string?
My legs are as long as yours. My legs and yours both reach from the ground underneath our feet to the point where they join to our rumps we sit on.

So our legs are the same size, not too long and not too short.
The question about the sisters was given to a zen student by a zen master. The student was obsessed with koans, or "instructional" poem / riddles that hopefully could lead to enlightenment.
The point the master was making was none of us can ever be sure of anything fully. We can only make guesses, educated or not. There's no way to say any thought, idea, person, machine, ... anything is ever right or wrong. How could it be fully proved?
As a secondary point the master had a trump card. The student responded with this. "Oh great master, I've studied the koan long and hard and can only conclude with another question, ... what does it matter?" In expressing this to the master who by then was grinning, the student was enlightened. The master winked and both went on their way.
The student realized that such a question was irrelevant to the way he needed to go. Did that then mean the koan itself was useless? Or was it useful to simply get the student thinking enough to realize it's uselessness? ... "I once dreamed I was a butterfly, ..."
Now to your riddle ... I'll guess an onion.
P.S. I need no help getting into trouble. I married her.

And no, I did not read ahead before answering the riddle, at least not here.
