Venomous from afar

Recently my wife posted these pictures of herself and our son on her Chinese social media page.
 Within the hour, her mother commented: "You have so many wrinkles around your eyes, you look older than me! You look old enough to be my older sister."
 To which my wife commented, "My mother is so nice".
 And her mom's reply, "I'm the only one here who is not too much of a pussy to tell you the truth."
