TLDR: Mom asked for my paystubs, I left them on the counter where she'd find them. She threw them away with some dishwasher trash and got defensive when I asked her to get them out of the garbage. She never apologized, and now I have to request new copies. AITA for thinking she should take responsibility?

Story:

My mom asked for my paystubs to help out with some rent/tax issues. I went and grabbed them and left them on the kitchen counter where she could easily see them. I had put in a dishwasher that day, so there were some garbage/manuals lying around from that, but I left the paystubs out in a distinct area, just on the same counter area.

Eventually, I discover that she had discarded them, believing that they were among the trash. They had gotten waterlogged in food and ordinary trash juice. I instructed her to remove them because she had discarded them herself, and I did not see why I had to dig out garbage for something she ruined.

Instead of apologizing, she was defensive and said that I shouldn't have left things on the counter originally, so I was "partly at fault." I disagreed—I left them there for her to see them, and she tossed them in the trash without even glancing at them. That's not my fault.".

She pulled them out of the trash, but they were ruined anyway, and she never even apologized. I now have to go request new copies from my company, and I'm still angry that she wouldn't simply own up to the mistake.

AITAH for thinking that people should be looking at papers, especially when they're not yours, before throwing them away?
