"If someone loved me the way Greg loves Margo, I wouldn't even consider my own feelings because I'm just a silly woman anyway."
Lu Ann, I'm a little fuzzy on the timeline here (have you even gone on your date yet?), but I'm going to go out on a limb and say that Greg and Margo don't have you and Peter beat by much in the "time before falling in love" department, so there's that.
(I guess how Greg "loves" Margo is very different from how Paul "loved" Lu Ann?.... Yeah, he's James Bond, it definitely is.)
