Unexpected changes in plans occur when circumstances shift suddenly, leading to a need for adjustments. This can happen due to various reasons, such as weather conditions, scheduling conflicts, or emergencies. These changes can affect personal, professional, or social commitments, often requiring quick decision-making and flexibility. When faced with unexpected changes, individuals may need to reassess their priorities and find alternative solutions. This could involve rescheduling events, altering travel arrangements, or modifying project timelines. Adapting to these changes can be challenging but also offers opportunities for creativity and problem-solving.
