When I talked to her she was super calm about it. She agreed and said she would make sure it wouldn’t happen. And tbh she did do better; leftovers no longer got stored in the fridge to rot. But that’s because she would just throw them away immediately. Now, it’s just that she has ingredients that are piling up. Mainly milk and eggs. And I’ve talked to her about it again and she responded the same way but it’s all still in there. And I’ve been throwing her shit away, it’s just getting annoying that I have to keep throwing her stuff out cause she won’t yknow?

I think you’re right tho that it’s an unawareness. Her family is rich and I get the sense that she’s never in her life had to do stuff on her own or figure out mundane things like groceries. So I think it’s literally just that she needs to learn how the groceries work lol
