She was having her hair and makeup done just before the meeting in the late afternoon with the emergency committee overseeing the rescue efforts.
The Hankyreh: As the Sewol ferry sank, Pres. Park was having her hair done
According to reports, the hairdresser and makeup artist go to the Presidential residences at 9:00 am on Monday, Tuesday, Thursday, and Friday. My guess is that President Park only works formally on those days and rests mostly on Wednesdays and weekends.
During the day of the sinking, which was a Wednesday, she was probably sleeping. Could she have been sleeping late and woke up around noon? Then decided to have her hair done before going to the emergency center. Her hair was deliberately slightly messed up according to the hairdresser, in order to make her look not so made up.
Nothing earth shattering, but it does show a President seriously out of touch with reality.
Choi Soon-sil helped her find cabinet appointees and run the country. What was the President doing? My guess is watching TV and movies. The Presidential Office had always been very sensitive to negative news, media, movies and other material about the President.
