    One day, little Tony went to a shopping center with his parent. It was very crowded. Tony saw a toy on a shop window. He liked it so very much that he quickly walked into the shop. After looks at the toy for some time, he turned around and found where his parents were missing. Tony was scared and begun to cry. A woman saw him crying and telling him to wait outside a shop. Five minutes later, Tony saw parents. Mom said, “How nice to see you again! Dad and I were terrible worried.” Tony promised her that this would never happen again.
