Frustrating Class

Rough day in class. One of my students got mad because apparently one of them thinks I am not fully going over the book. This student is not apparently going over the chapters I give them for homework,etc. I got upset and said, "This is college, not high school. I can't hold your hand and make you do your homework." So, she got pissed and walked out of class. I found her later and told her that if she has questions she has to speak up. Ugh. It's frustrating.
