You see a fairy fall over...

[Mysterian]

...so she decides to teach you a lesson.

"You laugh at my misfortune like a child, so today you'll be one, ya bitch!"

She turns you into a 4 year old and drops you off at a nursery. How do you spend your day?

I'll be mostly at the Lego table. I would also spell rude words with building blocks and innocently ask a grown up what they mean. I would do lots of paintings of monstrous people and tell the staff that I can see them to creep them out. Then I'd chill in the ball pit.

I would, with immense relief, curl up in the comfy cushions in the book corner.

Do I still have my adult brain just in a 4yo body?

You still have your adult brain. Just your body is 4. That's how fairies usually operate.

I’d go for a nap!

Paint some seriously disturbed paintings and make penis and balls out of play doh.

I'd stun the nursery staff with my precocious reading age by asking for a copy of War and Peace and settle down in the book corner.

Book section- i like stories and I don’t have any children so a lot of the books would probably be new to me.
