I just have to keep reminding myself that Lorelai doesn't know what we do. She doesn't know Luke couldn't get the song out of his head. She doesn't know that he was actually getting excited about what it might have meant. She doesn't know that he got her a necklace to show her he still cares. She doesn't know he overheard what she said to Patty and Babetter (and yes, I agree that was a badly written and directed scene, but it's what it is).
All she knows is that she made an embarassing, drunken display pouring out feelings she may not have even been ready to deal with to a man who has given no inidcation that he wants any more to be her friend and bantering partner again, and that the next time she saw him he practically shoved her out of his diner with coffee
to go and a muffin and donut he practically threw at her. I don't blame her for being cautious and trying to be all "whatever, dude" about it.
Now that I've made my peace with the fact that we're not going to get a true L/L reconciliation until (almost) the end of the episode, I'm kind of enjoying all the hijinks and misunderstandings. At least we know there will a (IMHO) good payoff.
I just really hope that all the specs are right and that L/L will take the boat trip together this summer. That would even be a good way of showing us that they'll have lots of time alone to talk and really work through things (along with . . . you know . . .all the other stuff they'd be doing on the boat

)
