A reactive person is someone who tends to respond to situations based on their immediate emotions rather than thinking things through. This means they may react quickly to stress, criticism, or unexpected events, often without considering the consequences of their actions. Their responses can be impulsive and may lead to misunderstandings or conflicts. In contrast to a proactive person, who plans and anticipates challenges, a reactive person often finds themselves responding to circumstances as they arise. This can affect their relationships and decision-making, as they may struggle to maintain control over their reactions in situations involving stress, conflict, or change.
