The dialogue of Willy Wonka in the last scene of Willy Wonka & the Chocolate Factory is not making any sense to me.
Willy Wonka: But Charlie, don’t forget what happened to the man who suddenly got everything he always wanted.
Charlie : What happened?
Willy Wonka: He lived happily ever after.
Here I was expecting something like the man who got everything must sacrifice a lot or something painful like that. Probably because Willy Wonka started the sentence with a 'But'. He had already given Charlie everything, and what else was there to say except something contradictory to the happiness. Yet his answer was something of a great positive value.
Is there any hidden meaning to this which I'm not getting?
