The catalyst: I was watching Gilmore Girls today. Season three. Kirk, the town eccentric, comes out of the pet store. He, armed with lots of cat supplies, is approached by the Gimore Girls, Rory and Lorelai. They proceed to have a conversation about Kirk's new cat, colourfully named "Kirk" or "Cat Kirk."
The debate: Wow, I thought to myself, this is so familiar. Not just because I've watched this very episodes multiple times before but I remember this exact concept of naming a cat after yourself. Therein arises the problem of two entities with the same name in the same household. This concept I remembered from a different context.
The realization: It all became so clear suddenly. This very situation I remebered from a Sarah Dessen book called "Last Chance" or "Keeping the Moon." In the book, the town eccentric (perhaps not to as an extreme degree as Kirk of Stars Hollow but still, he was a touch out there) is named Norman and he, like Kirk, has a cat named after him.
So I come to you with this proposal: coincidence or conspiracy?
I know that Ms Dessen is an avid viewer of Gilmore Girls and lists it as one of her favourite shows. I can only conclude that this concept arose from her viewing of Gilmore Girls and while, perhaps not an active choice to include this concept in her writing, the show so inspired her that her subconscious implanted this concept directly into her book.
