I guess it would depend on the situation. If it was a family thing that while not an emergency but important I would cut her some slack.. like a child was getting an award our something like that. Recently t contacted me on tthe day of an appointment to see if we could reschedule to the next or something. One of her close friends is end stage cancer. It was also this friend's birthday. Originally their group of friends gag planned to celebrate the birthday the previous weekend. However the friend was having bad. The day of my appointment she was having a good day. The group decided they should go celebrate that evening knowing they may never have the opportunity again. I rescheduled for the next day.
