On Friday, my mood was terrible. It was okay in the morning but it became bad in after English. In the book discussion, I was really angry of their behavior in the discussion because I am like the teacher of the group, I have to make them do the discussion when they are chatting= = whatever some of them even don't know I am angry! or don't know why I am angry. So I want to change the group quickly. People cannot in the same group with friends I think.
