Which of the following remarks could be classified as a cliché?

A remark classified as a cliché is one that is overused to the point of losing its original meaning or effect. In this case, the phrase "It will be over before you know it" fits this definition perfectly. This expression is often used in various contexts to reassure someone that a challenging situation or experience will pass quickly. While the intention behind the remark may be to comfort someone, it can come across as superficial or lacking in genuine understanding of the person's feelings.

On the other hand, the other remarks are more personalized and demonstrate active listening and engagement. They involve specific questions or invitations for discussion, indicating a willingness to help the individual in a more meaningful way rather than relying on a common phrase that might not resonate with their specific experience.
