Warm spring, a crooked distortion curve of the muddy path at the foot of a small village in from the north, was slow to leave the wind out of the south, crashed into the sky, break into rays of gloomy cloud.He slouched on the road sign at the entrance to the village, with a unicycle beside him.He watched the children ride in the colorful buggies, and the two wheels were singing happily on the stones.An old man was driving a tricycle, with stones in his car, and three wheels holding on to the prospect of a new house in the mud.A long haired young man was driving in a car that was not shiny, and four wheels went wild with a patch of mud.He remembered the lively evening of many years, and he sat with excitement in the audience, with his child's hopes on his face.After a cheerful music, a clown rides a wheelbarrow in a happy circle, from left to right, once upon a time.Shiny red nose, hairy curls, colorful clothes...That night, he realized what a real smile was: from the left ear to the right ear, a perfect radian always hung on the clown's face.The joy of the clown infected everyone on the field, and people shouted, "ok, turn around again!""Great!Make an upside down!"He remembered the clown who had changed his position in the car and remembered the perfect radian.At that moment, he wanted to be a clown, always happy, always smiling.Until one day, he really realized his dream.Watching his father's face down in a gully of sweat, he learned that life is not easy.He began to look grandiose, with a red nose and a "perfect radian" on his face.He like mercy of machine, single handstand on the unicycle seat, even causing not shivering, on the field but from time to time came the voice of cold: "lowly, should do the monkeys live."He threw himself to the ground, but he could only laugh and get up, and with a happy face, he could only slide into his stomach and fall to pieces and break his heart.Life is a drama, he is just a false actor.He was eager to bring a smile to others, but his own misfortune was the greatest joke.When he was a boy, he thought the clown was the most beautiful.And the mask of how many bitter tears he understood today.All he had was a unicycle: there was only one wheel to walk, and only one man to face life.Does he have a choice?After all, no one is willing to live in the cold and false world.Four wheels drifted apart.He felt the thick package in a pile of hundred dollar bills, with a sneer and a reluctant sigh from the unicycle.The four wheels creaked.Long hair youth look guilty, take out wet towel to apologize.Two wheels came laughing and laughing.The three wheels came up with laughter and relief.The perfect radian on a wheel, without disguise, from the heart.In the golden autumn, the air was filled with the joy of harvest.The broad asphalt walks through the village, sending the villagers to the distant future with a bright smile on their faces.He leaned lazily on the street signs of the village, felt the dry parcel, smiled, and stood beside him with a unicycle.
