"I think you're right," you tell her when it's your turn to input something into the conversation, "but I'm not sure I really grasp the depth of what you're saying. I would really like to get into this more, but with work and everything..."
"Yeah," she agrees, "I like that you're willing to take in another view point on it. We could go out for drinks and talk more, if you wanted?"
"Of course I do!" you say, then back it up a little. "I mean, that would be nice, thank you."
She laughs a little and you schedule drinks for the evening. You've got a couple hours after work to prepare before you meet her there.
