Little Mike’s grandma died weeks ago. He missed her very much. One afternoon Mike went to the city park where his grandma used to go. There he saw an old lady. She looked very kind. She was sitting there, watching pigeons(鸽子).Little Mike went up and sat next to her. He took out his food and drinks and gave some to her. She smiled at him. Her smile was so sweet that Mike wanted to see it again. She seemed to understand him, so once again she smiled. Mike was very glad.

They sat there all the afternoon, eating and talking. As it grew dark, Mike got up to leave. Before he left, he hugged the old lady and she gave her sweetest smile.

When Mike got home, his mother was surprised by the look of joy on his face. “I met a granny in the park. Her smile was like the kind of smile I had seen on grandma’s face.”

Few Americans remain in one position or one place for a lifetime. We move from town to city to suburb, from high school to college in a different state, from a job in one region to a better job elsewhere, from the home where we raise our children to the home where we plan to live in retirement. With each move we are forever making new friends, who become part of our new life at that time.

For many of us summer is a special time for forming new friendships. Today millions of Americans vacation abroad, and they go not only to see new sights but also with the hope of meeting new people. No one really expects a vacation trip to produce a close friend, but the beginning of a friendship is possible.

The word “friend ” can be applied to a wide range of relationships ---- to someone one has known for a few weeks in a new place, to a fellow worker, to a childhood playmate, to a man or woman, to a trusted confidant.
