Both my younger sister (16) and I (18) attend the same high school, and like most other kids without a reliable personal computer during the pandemic, we were both assigned chromebooks with chargers to be returned when we either left the school district or graduated.

A few years ago, when I was a sophomore, my chromebook was having a lot of trouble loading up certain apps before it stopped loading them up at all. Because of this, I had to seek out my school's tech support, which led me on quite the search because their communication was kind of spotty and they didn't have a lot of free time. Eventually, I managed to go in during one of my lunch periods and get the issue solved. I'm now a senior, and will be returning both the chromebook and its charger in a few weeks.

The problem now is with my younger sister's chromebook charger. It completely stopped working even though it didn't have anything wrong with it visibly. As such, I told both her and my parents that she should try emailing tech support to either get it checked out or get a new charger. They both agreed, and my sister said she'd email them by the end of the day while she borrowed my charger so her chromebook didn't die while she worked at home. I'd gotten my own computer and a charger to go with it at the beginning of this year, so I was fine with it.

She kept using my chromebook charger, which isn't that big of a deal, but since that was the charger that normally stayed in my backpack for emergencies at school or the library, I asked her when she'd asked to meet up with the tech support to get a new charger. She that she'd forgotten to email them and that she'd do it right now but then went straight back to whatever she'd been doing initially. I got a bit annoyed at that and told her to just do it because I wanted my charger back and she wouldn't be able to use it for much longer anyways, so she said fine and that she'd do it before going to bed that night.

It's been a few days at this point. She still hasn't emailed tech support and is still using my chromebook charger. I ask her again if she's emailed tech support and she says she forgot again and that she'd do it right now. I get annoyed once again at this and tell her that if she doesn't email them in front of me, I was going to take my chromebook charger back. She got upset at that and tried to get my parents involved before eventually asking me again where she was supposed to email. I know it was petty, but I told her to find the email herself because it was her issue.

She blew up at me when I said that, saying it wasn't fair that she had to do the work herself when I already knew where to look to find the email. She then tried to get my parents involved once again, but I still refused when they tried to ask me where she was supposed to email. I told her again that she had until the end of the night to at least send an email to tech support asking about the issue or I'd be taking my charger back in the morning. She stormed into her room after that, and now my parents are trying to get me to give her the email to "make it a little easier on her." Even though I agreed with them a bit, I said that she was the same age I was when I had to figure out completely on my own, so she should be just as capable of doing the same.

So, AITAH?
