(from the website for Anne Wheeler's movie)
This movie is one of the traditional lesbian romantic comedies that we all watched in college, complete with happily-ever-after and cheesey one-liners. You'll have to see it for yourself if you want to know where the taupe-and-lime reference comes from, but suffice it to say that it's a movie full of people going after their dreams. Lila, the main character's mother, says to her daughter at one point, "Margaret, there is no future in the arts!" And then, because it's a movie, everyone ends up with a successful career in the arts. But the point is not really that. The point is more that, when the movie starts, everyone is stuck. But by the end of it, they have all jarred themselves loose by facing their fears and taking chances.
So there you have it. Go rent the movie if you haven't seen it. It will make you feel all warm and fuzzy at the end. And, for the straight audience, yes, it's totally realistic for your girlfriend to break up with you for not saying that you love her in front of your mother after something like three days.
