The term 'Sulk Aimlessly' can be summed up by the word 'MOPE'. Moping is a behavior that involves feeling sad, lonely, or bored and expressing those feelings through a lack of energy or enthusiasm. It is often seen as a form of passive-aggressive behavior, as it can be used to express displeasure without directly confronting the source of the problem. Moping can also be seen as a way to avoid dealing with difficult emotions or situations.
