Il faut faire *son* lit

Question

In one of the questions the expression `Il faut faire son lit` was translated as "You must make your bed".

Is `il faut`, like `on`, requiring the use of the 3rd person?
Would it be grammatically wrong to say `Il faut faire ton lit`? What about 
`Il faut faire mon lit` if it's my bed that you must make?

Thanks you in advance.

Accepted Answer

Bonjour Antonios,

Both "il faut faire son lit" and "Il faut faire ton lit" are correct, but there is a slight difference. If I say "ton," that means I'm talking to you, Antonios, specifically.

"Il faut faire son lit" is speaking generally - everyone must make his or her bed. In English, we can also use "you" here, meaning not specifically you, Antonios, but you/everyone in general.

Yes, you can also say "Il faut faire mon lit, il faut faire notre lit," etc.
