I would rather listen to anything--a dentist's drill, a seal's mating call, Santa's snores, literally ANYTHING--than listen to you prattle on about where your head is at in regards to our blossoming relationship. Do you know why? Because it's only our first date. We haven't even received our food yet, much less entered into anything remotely resembling a relationship. I hate to bum you out, especially when you just bought me a nice beer with a respectably high alcohol content, but I really could not care less about where your head is about "us."
Frankly, I resent this entire set up. I'm a captive audience boxed into this restaurant booth. I have to make eye contact with you as you detail every nuance about where/when/if/how you will be able to enter a new relationship. Should I be taking notes? Will I be quizzed on any of this later? I'm so silly; I thought that you asked me out to dinner, but apparently you hired me for a therapy session. I feel like I'm getting a book report on your emotions.
That's great that you want to be upfront, but this little prepared speech that you're giving me is an insanely huge turn-off. While I'm being honest, [n.b. I would never actually tell a guy any of this] I'm seeing three other guys right now and out of all of them, you're the one I've hooked up with the least. It's totally fine that you aren't ready for a relationship. I'm not even sure if I want to kiss you later tonight, much less if I want to be your girlfriend. And, I don't appreciate you assuming that I want to be your girlfriend anyway. As Stephanie Tanner would say, "How rude!"
