He won’t let me throw the food away. He says he’ll eat it and that it’s harmless because that’s how they developed penicillin. Can someone help me out? Something seems off here. He’s yelled at me for throwing away moldy food before, it drives me insane.

He would rather buy too much food to the point where it molds than just buy the actual right amount. He always says “I just bought it yesterday” no matter if it’s been two days, or even over a week.

Edit: explain like I’m 5 why my hunch is correct or false about the mold plz so I can show my roommate. Although he’ll likely immediately argue and deny even if presented with corroborating evidence
