The bad day.
I went to the University yesterday. I haven't done my homework for Math the night before, but I was hoping that the teacher will not ask me. The Math began. The teacher asked me homework. I could not answer his questions. I got a bad grade. I was sad. The lesson ended. I walked down the stairs. I fell down. I had pain in his leg and head. I come home. I had a headache, but I did my homework in mathematics. This bad day was teaching for me.
