Formerly, when I was a reasonably young person, there were certain things about reasonably older people that I could not understand.  Like, the slipping eyeliner bit.  A well-groomed woman of a certain age, who was bandbox (i.e., model) perfect–except that the eyeliner on that one eye was askew.  Just a bit, but enough to notice. How could she? Didn’t she look in the mirror before she left home? 

Yes, she did.  And she noticed, but she just didn’t give a shit.
