So I actually have a real story:

My dad's housekeeper is illiterate. She's the mother of a woman who works in his office, and since he's only home three days a week and she needs work, he hired her as a housekeeper. Thing is though, he can't leave instructions for her or send her texts (she does have her cell phone), so everything has to be communicated vocally, so mistakes happen ... a lot.

A couple of months ago, I moved home to wait for a job to start, and I guess that threw her out of her comfort zone, since I'm a really private person, and I like my things set up a specific way. Every week she would come home and clean, and every week, I would have to dig through my dad's and sister's clothes to find them and replace them. She did this with a lot of things, to the point where I forced my dad to call her and have a talk with her.

Things got better for a month or so, then my stuff started mysteriously disappearing. At first I thought things were just being moved again, but no, they were gone. A pair of headphones, loose change, etc. One day, my dad's iPad was permanently locked, and my laptop had been closed so fast that the screen had fallen off the hinges (side note: Don't buy HP. Don't ever buy HP. The plastic they use for their laptop casing literally can't support its own weight so snaps off after a couple years, which was why I never closed mine anymore). I tried to tell my dad, but he wouldn't buy it, until one night he noticed the the silver thumbprint engraving of my mom's, which the funeral home gave us after her funeral, was gone. That was the last straw. He decided that the next day, he was going to have to call her and fire her.

Then the next day came, and while we were discussing the issues, we both realized: what would an illiterate person be doing trying to access an iPad? Or trying to use my laptop? Or stealing headphones when the most high-tech item she owns is a 10-year-old flip phone that doesn't even have texting? So instead my dad waited for her to come back next week, sat down and talked to her, and found out: She had been bringing a granddaughter in to help around the house. The granddaughter was the one who had stolen things and tried to access our computers, and the housekeeper was able to get our stuff back. Since my dad works with the lady's daughter, he decided it wouldn't be good to fire the housekeeper just for trusting her own granddaughter, so he forgave her, contingent on the stuff coming back, which it since has.

So, tl;dr Being illiterate saved our housekeeper her job.
