Can you tell me something about it?

First of all, if you usually have a good relationship, then I don't think Party B wants to order you. He may just think that your relationship can be close enough to say such a thing, so he blurted it out naturally. But if you two don't get along well at ordinary times, then he may be deliberately trying to order you to achieve his goal. You said you could ask someone else. I think you have politely turned him down. You are uncomfortable with what he said. Of course you can solve it in your own way. Obviously, you did a good job, not only rejecting others, but also not making the relationship so stiff. In the workplace, you should learn to refuse and be tactful. This is the long-term way.

Send you flowers.
