you sure about that? ;)

Hey babyeggplant (dude), I got the 沙发，哈哈。

沙发～

Here it's kind of like "see if."

See if you can bring me a book next time you're out on business.

Here it means to 'consider'.

If this is a Chinese person talking to you, I find the use of 能不能 kind of interesting -- it is super polite in English, but my experience is that they are asking you to bring them a book.
