"Your desks are small."

Translation: 너희의 책상은 작아요.

[xXBad_WolfXx]

Why do I have to use "너희의"? Does this mean "you all"? In which case, can't one person (i.e. a salesman) have many desks that are small, so "너의" would be acceptable?

Eeeh it can be yes but.... it is not normal case !

[Le_choc]

I'm still kind of confused. Do people actually say 너희의?
