想要邀请别人，约会是appointment，但是怎么表达，或者跟老板沟通一下工作。

Can we meet on the 14th?

Can we meet next Friday?

Are you available on the 14th?

Are you free next week?

Accepting an appointment:

Sure. I’ll come.

Yes, Sunday is fine.

Friday would be perfect.

拒绝表达时候可以用一下说法

Sorry. I have another appointment at that time.

I’m sorry. I can’t come.

I’m afraid I can’t on the 14th.
