"I don't have anyone to play with," Bob said."I wish we stayed in Salt Lake City.I
have friends there.'

with red hair."Hello," she said,"I'm Mrs.Graney.I live next door.I came to ask for two

eggs." "You may have the eggs," said Mrs.Miller."But sit down for a moment.Let's have
coffee and talk a little.'
That afternoon there was another knock on the door.It was a boy named Tom."My
mother told me to send y6u this cake and these two eggs," he said.Bob asked him to come in

friends.
