TV deals in very broad strokes. Like, 'Oh, that's my dumb friend', or, 'That's my funny friend.' A true best friend, a sidekick, has to be a little deeper then that. You have to feel like there's nothing either character won't do. That someone really, really has their back.

Willie Garson’s quote emphasizes the difference between superficial portrayals of relationships on TV and the more complex and authentic dynamics that exist in true friendships. He points out that television often simplifies relationships into broad stereotypes, such as labeling someone as the “dumb friend” or the “funny friend.” While these labels may serve as easy characterizations for TV, they fall short of capturing the depth and loyalty that are essential in a genuine friendship.

Garson then contrasts this by suggesting that a true best friend or sidekick needs to be more than just a comic relief or a one-dimensional character. He believes that the bond between true friends runs deeper, built on a foundation of trust and unwavering support. In his view, a real best friend is someone who is ready to stand by you no matter what, implying a level of commitment and sacrifice that goes beyond surface-level interactions.

He also highlights the mutual dedication that defines an authentic friendship, stating that there should be nothing either person wouldn’t do for the other. This speaks to the idea of shared experience and the sense of solidarity that comes with a deep friendship, where both individuals are emotionally invested and willing to support each other through thick and thin.

The origin of this perspective likely comes from Garson’s extensive experience in acting, particularly his role as Stanford Blatch on Sex and the City. In portraying this dynamic, Garson would have developed a nuanced understanding of the complexities of friendship and the importance of loyalty and support in relationships. His reflection on TV’s portrayal of sidekicks and best friends contrasts the industry’s tendency to rely on clichés with the reality of what it means to have someone who truly has your back.
