A baby can smile and cry without being taught to do so. Yes, smiling is an easy thing. But you may not do it well.

　　Sometimes, when you take a walk in a park, you might see an old woman sitting on a bench. If she were to smile at you, you’d probably smile back. Or you might see a boy flying a kite, you’d probably smile at him too.

　　However, many times, when people see strangers smiling at them, they become frightened and wonder if that person might have some bad intentions. What a miserable thing it is!

　　With the development of the society, people have become less friendly to one another. They think it is of no use to smile to others unless it will benefit them in some way. So people smile at each other less and less.

　　Do you like smiling? Can you do it well? We need smiles in our lives.
