Explain the conversations David has with his uncle in the morning. What conclusion does David come to regarding staying at the House of Shaws?

The meal in the morning was porridge again, though two bowls were lain. However, the beer given to David was from Ebenezer's cup. David was amazed by his miserliness. Through Ebenezer's questions, the man learned that David's mother was also dead. He also asked about friends that David had referred to. David named the Campbells though he knew only of the one. Ebenezer thought the answer over awhile and then told the boy that he would think of a proper type of employment for him. David told the man that he had not willfully sought him and would be glad to leave if he wished. The old man reassured him, repeating that he would do right for him as long as he did not say anything to anyone. David then felt confident enough to ask for a better sleeping situation to which Ebenezer snapped angrily, before stopping himself and again reassuring the boy. David was reminded of Jennet Clouston, the woman who had spit at the thought of Mr. Balfour, and he told his uncle. Angered, Ebenezer dressed to leave and punish the woman, telling David that he would have to wait outside while he was gone. David refused to be locked outdoors, upsetting the old man but not budging on this point. Finally Ebenezer decided not to leave. Confounded, David inquired why the man wished to help him when he obviously hated and distrusted him. Ebenezer denied these charges, again reassuring the boy. David agreed to stay for a short while.
