Trouble. . . How did you reply to the message "Please call me back when you see it"?

In general, it depends on who you care about or who you don't care about. If you are an important person to yourself, you may be worried about you. In addition, if you are at work, you must return, but if you don't care about people, you don't have to return, wasting your phone bill, not to mention keeping it in your heart and wasting your feelings.
