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.
