Trick

My girlfriend told me she had been the victim of natures cruellest trick...

there are women out there who are like that. I think they say things like that just so they can break up with you. If you say "That's sick, I can't believe you tricked me like that" they'll say "you never loved me in the first place! I'm leaving." However, if you say you support her, as the movie portrays, well...watch the movie.
