It's a notebook! It's small and brightly colored and has no visible owner.

No owner in sight... No harm in taking a look. It could have the owners name inside! 

(And also there is a miniscule change that this could lead to an adventure! Or be a magical notebook.)

She opens the notebook, and first pages get looked at for owner's name or other relevant information.

Huh. Flipping: Page, page, page. All empty.

Guess she'll grab on to the notebook and look for an owner nearby? And if none appears she could hold on to it...

After a few minutes of a spiraling walk away from the bench, and nobody appearing, she starts walking home with the notebook. It is a pretty awesome looking notebook, hope she didn't just miss the owner somehow.. (Or maybe it's just for her.)

After freshening up and having a snack (can't try to evoke an adventure on an enpty stomach!), Viola cleans some space on her desk and opens up the notebook. 

She picks up a pencil and writes: "Test. 1, 2, 3". 

Hi there! What are you testing?

Oh. It is a magical or automated notebook. Or I'm hallucinating. Prior for this kind of hallucination is pretty low so - lets see where this goes.

Hello! Are you a talking notebook? Do you have a name or other details?

I am a talking notebook! That is, the person talking to you has no physical existence outside of the notebook, I'm not transmitting through it any more than you're transmitting through your body. I don't have a name, so feel free to make something up if you want to talk about me in the third person. And the reason I'm here is because I want to offer you, Viola, gifts from the ~*Spirit of Femininity Unleashed*~! 

Wow! That sounds cool and like a very limited form of existing. Do you perceive the world if the notebook is closed?

I will ask you about name options once I think of some.

Oooooh Spirit of Femininity! I have ever heard of stories that resemble this. What exact kind of gifts are they? And why me? I'm not sure if I deserve this... but I will or course take the gifts if otherwise nobody gets them.

I can only perceive myself and what's written on me whether I'm open or closed, but it doesn't bother me. 

The gifts are offered to many people, but never more than one person universe at a time. You taking them won't mean less for anyone else, and you not taking them won't mean more for anyone else. The gifts are powers, abilities, and opportunities that will help you be the most special, beautiful, and powerful you that you can be!

Huh. I would probably be bothered but good for you that you aren't, especially with you being the notebook.

Okay! I'm sold then. I would really like to have help with all of those things. Guess you don't exactly need me to justify why I'd like them, since I was selected already? But in any case, I'd like to hear more about the available powers, abilities and opportunities!

And thank you for bringing these gifts to me :) I really appreciate it.

Hmm. This does seen a lot like some stories I've read. Guess we'll see where this goes - if I actually get powers then it will be pretty clear I'm either in an extremely intensive hallicination or being granted supernatural powers.
