。
She told me an interesting story.
Literal
She [topic-は] me [to-に] interesting story [object-を] did.
Note the absence of a benefactive ~てくれる on 話をした — without it, the sentence is neutral and reportorial: she did this thing, the speaker observes it. Whether it was a kindness or just an event isn't grammatically marked. 面白い ('interesting / amusing / funny') is one of the broadest Japanese adjectives — context determines whether it leans toward intellectual interest or comic appeal.
