Sulk, often referred to as pouting, is a behavior characterized by a sullen or moody demeanor. It typically occurs when a person feels upset, disappointed, or ignored. During this time, individuals may withdraw from social interactions, display a frown, or avoid eye contact, signaling their discontent. This behavior is common in both children and adults, often serving as a way to express feelings without direct confrontation. While sulking can be a temporary response to frustration, prolonged sulking may indicate deeper emotional issues that could benefit from open communication or support from others, such as friends or family.
