When John Gray, author of Men Are From Mars, Women Are From Venus tells you your relationship won't last, then it's time to pack it all in. I should know because I've read his book. I mean I skimmed it. Or just read the first chapter. Or looked at the cover once in a bookstore. Whatever, my point is that the man is so in tune with how relationships work that he doesn't even have to know you in order to deem your love life worthy or not. Recently, Gray said Jennifer Aniston and Brad Pitt's relationship was doomed from the beginning because apparently they're both too sexy, and "that kind of pressure makes it hard for a relationship to last." Finally, now I know the reason for all my failed relationships.
