A lady wanted a certain guy to come to her house and ate supper.
He said: You don't have to do it.
She replied: I know I don't. Her tone did not seem to invite dissent
Does it mean her tone was that saying "no" by the guy wasn't welcome?
I have to say that the comment by He seems a little strange to me. If it was clear that she wanted to invite somebody, then there appears to be no question of having to.
