LW#1:  "She obviously wants me to notice."  Uh, no.  She is not thinking about you as much as you believe she is, and obviously not as much as you think about her!  She's living her life and sharing pictures of it.  She's 45 years old -- she doesn't need your approval and what she does to her body is none of your business.  Unless she specifically asks, "so, what do you think about  my new tattoo?" don't bother saying anything to her.  It's none of your business.
