Mark drives by his ex-girlfriend's house and checks her social media to see if she is there. This behavior is an example of what?

This behavior exemplifies stalking because it involves persistent attention to and monitoring of an individual's activities, especially in a manner that can be intrusive or unwelcome. Stalking typically includes actions that are aimed at maintaining contact or gathering information about someone without their consent, often leading to feelings of fear or discomfort for the targeted individual.

In this scenario, Mark's actions of driving by his ex-girlfriend’s house and checking her social media imply an obsession or fixation that goes beyond normal curiosity or concern for a former relationship and suggests an unhealthy pattern of behavior. Stalking is characterized by a pattern of behavior intended to harass or intimidate the person, which can cause emotional distress.

Monitoring, harassment, and surveillance, while related concepts, do not fully encompass the legal and social implications that arise from stalking behaviors. Monitoring suggests oversight without necessarily implying an obsession. Harassment typically involves repeated unwanted communication or threats rather than just observation. Surveillance usually refers to careful observation with a specific purpose, often in a context like law enforcement or research, rather than a personal fixation. Thus, the correct identification of Mark's behavior aligns with the definition of stalking.
