I used to have a good relationship with the auto mechanic. I was an apprentice. We used to talk and laugh, and told me that together we were family and brothers. Ever since I came.

I think we should first find out whether it is because of the middle school students that the master has changed his attitude towards himself, or we can talk openly. Sometimes silence can easily lead to misunderstanding. Maybe the master is just in a bad mood or dissatisfied with himself for other reasons, so that finding the crux of the problem can really help solve the problem. I also suggest that I study technology well. Of course, a master teaches an apprentice who likes to be diligent and eager to learn. We should try our best to change ourselves and let the master see our efforts.
