Last Monday, I was informed to host the graduation ceremony with one of my classmate in our school hall. Faced such a great opportunity, we both feel excited. In order to make the ceremony successful, so we made enough preparations for it. They arranged the programmes, got familiar with the words and practised a lot together.
When I got on the stage, I was so nervous, beyond my control, which I made the mistake. What an embarrassed moment! Just then, I noticed my teacher smiling at me. Because his encouragement, I calmed down and everything worked out smooth as expected.
