Situation is a couple living in a small flat.
Person 1 is using the bathroom, washing hands. Person 2 enters the bathroom and person 1 exits the bathroom quickly, forgetting to turn off the tap.
Would you think that this is a sign that person 1 is in a bad mood or upset with person 2?
There is previous history as person 1 has done it before when person 2 enters the kitchen (eg they leave the cupboard or dishwasher open and just leave)
