JESS: I’m not playing Golden Retriever, hoping one day she’ll turn around and fall in my arms. If she doesn’t wanna be with me, then fine.
The Golden Retriever is a dog breed which originated in Scotland in the late 19th century. They are known for their thick, golden coat, and their gentle, affectionate nature. They are extremely popular pets, because of their calm, biddable temperament, which makes them easy to train and eager to please. Jess must see Luke as being like a sweet, snuggly Golden Retriever, adoringly waiting for Lorelai to give him tasks to perform.
