If my friend were to say to me, "I'd like to have dinner with you," which would it be more correct for me to say in response: either "I'd like to have dinner with you," or "I'd like to have dinner with you, too?" The latter seems incorrect because the "you" I'm talking about (my friend) is not the same "you" that he's talking about

. It seems like you would use "too" only if there were a third person involved. For example, if my friend says, "I'd like to have dinner with Sam," and I also want to have dinner with Sam, then I would say, "I'd like to have dinner with Sam, too." But if the person the speaker wants to have dinner with is different (my friend, with me, me, with my friend), "too" seems incorrectly applied.
