i'm going to bed - You're acting like Hermione Granger from The Philosopher's S

You're acting like Hermione Granger from The Philosopher's Stone, but you're just tired and you don't want to be smart anymore.

I'm going to bed like Hermione Granger because I'm too tired to be smart.

Right I'm going to bed, I want to be a normal person for once.

I'm going to bed and I'm not coming back until I’ve finished my potions homework.
