I often get caught up in self-accusation. It's a terrible feeling. Tonight when I leave my friend's home, I think she was playing Majiang, and i was afraid that my little daughter would cry and didn't want to go home. So when my little daughter agreed to go home, I took her leave without saying goodbye to my friend who was on upstairs. Playing Majiang.After I called her I felt her ill humor and I realized I was wrong. So sorry to my friend. I should say goodbye to you before I left.
