Someone in the house is eating other people's food.
" I am currently flat-matting with other people, recently the household has been experiencing weird situations where other roommates food goes missing. Today I saw that a huge chunk of my cooked lasagna was eaten with the spoon put back. For those who think I did it, and is just trying to falsely accuse someone, no. I didn't have lasagna for dinner last night, I just ate a pie and that's it because I wasn't too hungry. I am actually so disgusted and now I don't want to eat the rest of the lasagna because whoever did what they did now put their germs on my meal."
