Oooh. Your joke wasn’t very clear. Because she did become hungry again, because thats how it works in our linear time.

Attributing the act of sharing being something that retroactively removes the action IS absurd, youre right.

It just wasn’t a very clearly executed joke.

A well placed /s would help. Or further elaboration of the joke to emphasize the absurdity.
