Rifts are a common cause of bickering. They are disagreements between two or more people that can lead to arguments and resentment. These disagreements can be caused by a variety of factors, such as differences in opinion, misunderstandings, or a lack of communication. Rifts can also be caused by external factors, such as financial issues or changes in lifestyle. Regardless of the cause, rifts can lead to bickering and can have a negative impact on relationships.
