    Last Friday, I learned a lesson about telling lies. Early in morning, I didn't want to go to school, but I pretended to feel ill. My mother was very worrying when I told her. She left quickly and I thought she has gone to work. But soon, she came back with a bottle of medicines. She said that she had asked for a day off work to look for me. I felt a little guilty but I dared not tell the true. That afternoon, my teacher came to visit to me. I felt so regretfully for telling lies. I had wasted anybody's time. Finally, I admitted I had lied and promised never to do it again.
