I don't think it sounded like the first date when horrible.... sometimes it's just awkward. When I started dating this one gal a while back we talked for about an hour or so over dinner and then the conversation seemed to die out. I thought to myself, "Oh goodness we'll never go out again"... ended up dating for another year... didn't work out in the long run but 1 date is hard to tell by.
As far as opening doors, etc, etc... pretend you are her secret service man, butler, door man, and everything else. Open the door like a doorman would do, pull out a chair like a butler, and open the car door like the secret service... make up some other stuff too... makes it fun... in your head... 😛
