My parents and I went to the park last Sunday. There were lots of visitor standing in front of ticket window. We waited a long time and buy three tickets. In the Tiger Mountain of the park, I was too eager to see the fierce frightening animals that I quickened their steps through the crowd. Unfortunately, I got separated from my parents. I had a hard time look for them, but I had no lucky. Wandering in the park, I felt alone without any companions. Bad still, I had no money, so I had to walk to home, covering as much as 5 kilometers.
