What behavior often involves physically pursuing another individual?

The behavior that often involves physically pursuing another individual is stalking. Stalking is characterized by repeated and unwanted attention and contact from one person to another, which frequently includes following or tracking the individual without their consent. This persistent behavior can create a sense of fear, anxiety, and distress for the person being pursued.

In contrast, harassment generally refers to a broader scope of aggressive pressure or intimidation, which may not specifically involve physical pursuit but can manifest through various forms of communication. Negligence relates to a failure to exercise appropriate care in a situation, leading to unintended harm, and does not involve pursuing someone. Discrimination involves unfair treatment based on certain characteristics, such as race or gender, rather than a direct pursuit of an individual. Thus, stalking is the most accurate description of the specific behavior framed in the question.
