Please choose the correct ending to complete the given sentence: Relationships: [header] How to have a pleasant facial expression [title] Know how your face naturally rests. [step] Resting facial expressions aren't always a direct correlation of how you're feeling. Many people simply have a serious disposition.

Ending1: In no time though, you likely will have noticeably lowered facial expressions. That has to be a sign of maturity. Ending2: This makes it a potential indicator that you are in need of a facial. Knowing how your face mostly rests on the line between your eyebrows is another important indicator of whether you are happy or upset. Ending3: Those who haven't been looking out a window or responding to a major noise or traffic are more likely to daydream or slouch. Equally important is sitting down and focusing on the task at hand. Ending4: This creates an uninviting demeanor. Take a picture of your resting face and look at the expression.
