Example: 
The lighted bus appeared on top of the next hill and as it approached, they moved out into the street to meet it. He put his hand under her elbow and hoisted her up on the creaking step. She entered with a little smile, as if she were going into a drawing room where everyone had been waiting for her. While he put in the tokens, she sat down on one of the broad front seats for three which faced the aisle. A thin woman with protruding teeth and long yellow hair was sitting on the end of it. His mother moved up beside her and left room for Julian beside herself. He sat down and looked at the floor across the aisle where a pair of thin feet in red and white canvas sandals were planted. His mother immediately began a general conversation meant to attract anyone who felt like talking. 'Can it get any hotter?' she said and removed from her purse a folding fan, black with a Japanese scene on it, which she began to flutter before her. 'I reckon it might could,' the woman with the protruding teeth said, 'but I know for a fact my apartment couldn't get no hotter.' 'It must get the afternoon sun,' his mother said. She sat forward and looked up and down the bus. It was half filled. Everybody was white. 'I see we have the bus to ourselves,' she said. Julian cringed.
