From the dialogue, what was the relationship between Jia Zhengyun and Jia Baoyu?

In chapter 17 of 'Dream of the Red Chamber', Jia Zhengyun and Jia Baoyu had a conversation from which one could infer their relationship. "Young Master, you're early this time." "It's getting late. I just came back." "I don't know what Young Master is busy with, but why didn't you say anything today?" "You don't have to ask. I'm too busy." You rest for a while and wait for me to finish my tea before we talk." From this conversation, it could be seen that Jia Zhengyun was somewhat dissatisfied with Jia Baoyu's attitude. He thought that Jia Baoyu was too busy and didn't even say a word, as if he didn't value him. However, from Jia Baoyu's reaction, it seemed that he was not really angry. Instead, he asked Jia Zhengyun to rest first and talk after drinking tea. From this, it could be seen that the relationship between Jia Baoyu and Jia Zhengyun was not close, and might even be a little distant.
