Why did no one teach me what a nut is?

In the last six weeks or so a suspicious amount of stuff has broken in Mia's apartment and her landlord isn't exactly the best when it comes to fixing things well or quickly. She thought about trying to fix some stuff herself but it turns out she didn't inherit the "handy" gene from her mom. To be honest, she doesn't know the difference between a washer, an anchor, and a nut.
