XXX: Insomnia for her.
In college, I remember, you don’t sleep for a day, you lie down for an hour and another day. And then you go to the exam, push yourself off the ground and jump into the audience window. Everyone is in horror, the predator smiles, you take him by the hand and you have fun running with this cheerful grandfather to the park for ice cream. The conductor pushes in the shoulder and polently asks you to pay for the second round... and you go home to teach for another day to go with the other group.
XXX: and no problems sleeping between sessions.
