I'm an Asker but I don't know why I was downvoted. Two months ago I saw a woman in a coffee shop and hit on her. I invited her to go out with me and see Taming Your Dragon In 3-D. She declined and said it was lame. But she took my number and said she'd call me and invite me to a beach party some time. I never got a call from her, and even saw her again in the same coffee shop, but didn't bring it up. She called me today to invite me out this weekend to a beach party. My point is that you can never predict these things. If someone is giving you the "polite yes" or the "polite maybe" but is giving you bad vibes via body language, then you can use that to help gauge your interpretation.
