Help me analyze the meaning of the boss's short message.

In fact, all you have to do is reply with a "thank you". Talk too much, the boss thinks you love him. As for "good", it means that you are reasonable and can understand people. For example, he may smile at you and say a good word or two. It is the most important thing to do your job well, draw a clear line between public and private, and win respect. Wish you a happy life!
