What does the QQ signature written by my wife mean: youth is something you don't keep, calmness is something you don't explain, true love is something you don't let go of, and life is something you don't want. I agree that the woman upstairs likes to use the good sentences she saw as her QQ signature. I feel that your wife's signature shows that she is satisfied with the status quo and confident. This satisfaction may have nothing to do with you, but may be satisfied with having an affair with another man. Bottom line: She is happier now.
