What are three objects you couldn’t live without?

This question makes it too easy to be a smartass. Water, oxygen, and food – durr. However, I assume – at least I hope – that the author (authors?) of this prompt doesn’t mean it so literally.
On a superficial level, I am first and foremost a reader. A book junkie. And sometimes (most times), a book adulterer. While I’m reading an 800-page novel, I’m listening to a smutty audiobook on my walks, and a graphic novel when I need some down time. Factor in anything I have/choose to read for work and I’m a bonafide book slut. So it’s obvious which superficial item makes it first on my list – books. And this includes ebooks, audiobooks, magazines and literary publications – basically any reading material I have on my shelf.
The second item – or should I say items – on my list are basic writing contraptions. That’s right, I’ll need a journal (or loose-leaf paper if you don’t care for order), a pen, and maybe something to correct my mistakes with. Writing mistakes, that is.
And the third item is something most people fantasize living without, but not me. No sir, ma’am, and non-binary individuals. The third thing isn’t the most important, but is still just as important. For it can hold my books and act as a writing contraption. But it can also keep me in touch with friends and family while also showing me cute videos and pictures of cats. That’s right: It’s my phone.
Now, I can hear you already – “Gwimo, you can live without your phone!”
Can I, Alice? Can I really? Do you understand how heavy 800-page books are? Do you understand that sometimes I want to listen to an audiobook? Do you understand that carrying around a journal and pen everywhere can be impractical? Sure, nothing beats physical books and journals, but there are times when I just need something that fits in my pocket.
So there – those are my three non-smartass, non-essential essential objects that I can’t live without (though, I probably could).
