My parents and I went to the park on last Sunday. There were lots of visitors stood 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 over the crowd. Unfortunately,
I got separated from my parents. I had hard time looking for him, but 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 home,
covered a distance of 5 kilometers.
