Sorry Professor

In Chem class, we got our course grades passed out yesterday while doing classwork. Most students were conversing amongst each others, while others were staring at their grades (me), and others were attempting work problems. My professor went over an objective, so that we could move on to the next. She was explaining and showing the answers on screen. Then she was like, "Okay now you can move on and stare at those problems." Omfg she was so done with us. ><
