You should always clean up your messes.
Roger and Diane are in the kitchen and Roger has the fridge open as he finishes the last bit of the milk in the milk carton.
Roger wants to put the empty milk carton somewhere.
Roger walks over to the trash can and disposes of the empty milk carton in the garbage.
Roger looks at the milk carton and then puts it back on one of the shelves in the fridge.
Diane is happy to see that Roger is doing his part to keep their household clean and tidy.
Diane is annoyed that Roger is putting garbage in their refrigerator and is stressed out because she now questions his judgement.
