Which term best represents an event that is typically unwelcome?

The term "incident" is best suited to represent an event that is typically unwelcome. An incident often implies something unforeseen or unfortunate, such as an accident, disturbance, or conflict, which aligns with the notion of being unwelcome. When we refer to an incident, it usually has negative connotations, suggesting that it disrupts normalcy or creates a problem.

In contrast, "experience" can be neutral and even positive, encompassing both good and bad events. "Conduct" pertains to the manner in which someone behaves, and "exhibition" refers to a public display of works, ideas, or skills, typically seen as positive or celebratory. These terms do not carry the same implication of negativity or unwelcome nature as "incident" does. Therefore, the choice of "incident" clearly encapsulates the essence of something unexpected and undesirable.
