What does 'It's your party' mean as a figure of speech? After reading the book 'Harry Potter and the Deathly hallows', one doubt remained with me.
In the chapter King's cross, there is this dialogue between Harry and Dumbledore.
“Well, where do you think we are?” asked Harry, a little defensively. “My dear boy, I have no idea. This is, as they say, your party.”
Actually, this was the only thing that didn't make sense to me.What did Dumbledore mean by 'his party'?
