My sister has no idea how to preserve our food. My family is poor due to financial problems and difficulty, and my sister keeps on eating everything when she knows we can only afford to get groceries about 3 times a day. Shes constantly eating up everything, even when I told her about my secret stash of food I’m saving, she ate that too. It’s mainly because she’s got fast metabolism, but it’s still frustrating and she just keeps on eating.
