Since we were small, we have been educated it is not right to tell lies. Though I keep these words in my mind, I never learn until I made the mistake. It was a Sunday. I had made some plans with my best friend. When she called me on the phone, I felt so sleepy and told the lie that I was not feeling very well, the plan had to be cancelled. I continued to sleep. Then in the evening, she came to see me with present. When my mother calling me, I pretended to be sick. I felt so guilty. I had to tell so many lies to cover the first lie. Since then, I promise not to lie again, because the price of lies makes me tired.
