After inviting the girl to lunch, she sent back a message saying; Invite you to dinner next time ~ what do you mean?

If you want to invite a girl to lunch, and then she sends you a message saying that she can invite you to dinner next time, maybe she doesn't refuse you directly, but indirectly. He can't eat with you at noon, or he didn't mean to eat with you. At that time, the girl only said that because she didn't show up when she refused you. Maybe you need to understand whether he really rejected you or for a pretence. Try again next time and see what his answer is. If he agrees next time, maybe he is real this time, just because he has no time. If he doesn't agree next time, then he is true, and this time he is rejecting you in disguise. What a girl sometimes says is obviously a sentence, but you can't understand it as a sentence. You have to think about many meanings behind it. Girls often need you to guess the implied meaning of what he said.
