recently you are often busy working, and every day you bring lunch because the coffee machine there is broken, but the strange thing is that every time you bring your lunch, when you open it, it's empty

of course it makes you angry and surprised, it continues until 3 days later you want to interrogate who ate your lunch, at that time you hide and see someone open the refrigerator door which contains your food, then he takes your lunch

"Hmm, the lunch is new and looks delicious"
