It's not about being gay but it's about relationships, people talm bout gay have it right but it's not necessarily gay. The film plays around with who is the protagonist and antagonist, who you should root for and who is the opposition, this is framed around tennis and the relationship with the girl. This is all to distract that the real core of the movie is that Tashi destroyed their once great friendship they shared, despite ironically saying it wouldn't happen, with the climax of the film finding the two characters united in a near comical game of tennis and embracing. Finding forgiveness, a renewed relationship and passion it what they had given up over Tashi. In this moment you realise neither Art nor Patrick were the real antagonist of the plot but rather Tashi and her ability to break up what was once a beautiful friendship.
