While external events or situations can indeed trigger stress in a person, stress is ultimately a subjective response to those events or situations. Stress is influenced by individual perceptions, thoughts, coping mechanisms, and past experiences. Therefore, two people can experience the same event, but one may find it extremely stressful while the other may not be affected much at all. This subjective nature of stress demonstrates that it is not solely caused by external factors, but rather a combination of external events and individual responses.
