This morning, M woke up at 8:30.  We had stuff to do so she did not have her normal morning routine but instead immediately felt the pressure of being rushed.  At 10:30, after the pressure was relieved and she had had a moment to relax, I asked her to help her sister with a task.  She quickly became agitated and yelled at her sister.  When I pointed this out, she voluntarily went to her room to calm down.
