My parents and I went to the park last Sunday. There were lots of visitors stand in front of the 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 frightened animals that I quickened my steps through the crowd. Unfortunate，I got separated from my parents. I had hard time looking for them, and I had no luck. Wandering in the park，I felt alone without any companions.
Worse still，I had no money, so I had to walk to home, covering as much as 5 kilometer.
