Bob comes out of the station and at once he doesn't know where to go. He comes to see his good friend, Peter. Peter is a worker. He works in a factory, but Bob doesn't know where the factory is.
He walks along the street. He passes a hospital, a post office, a bookshop and at last he gets to a school. Some students are coming out, so he asks one of them," Excuse me. Do you know where the Red Star Factory is?"
"Of course, I know. I live near there. My father works in that factory. It's outside this town," answers the boy.
"Is it far from here? Can you show me the way, please?" Bob asks again.
"I'm going home now. Will you come with me? We can go there by bus. "
