My boss told me never to go to work again.
Why?
I don't know. When he told me that, I was very sad and surprised.
Do you often go to work late?
Yes, I often do.
Do you work hard?
Well, it's hard to say. It depends.
Are you good at the computer?
No, I don't know how to use it.
Then I know the reason. You didn't use your time well and you don't learn new things.
