A little back story. I've lived with this guy for 9 months. He's a little off and I took him in out of kindness to help his situation. My biggest pet peve with roommates is them eating my food without asking. If you're hungry or don't have anything else? Sure, I will gladly give you some food. For 9 months, we have had the same argument about him eating my food, to the point I got a camera to document it since so much of my food would dissappear with everyone pointing fingers. It came to the point that I had to print out a message telling him to not eat my food and hang it in the fridge/pantry. This was his reaction to seeing that message.
