The car belongs to the friend

In a relative clause, we do not use words like he or she after who or which. This is because who and which take the place of

he or she

Example:A man who he spends all his money is a

fool.

A man who spends all his money is a fool.

In informal English, we often leave out the relative

pronoun.
