Yes, I thought the run on sentences might be intended to duplicate the mental state of your first-person narrator. In that case, I have only THREE suggestions:
The second sentence of the fourth paragraph has an awkwardly placed parenthetical comment (sans parentheses). I recommend moving "for months" so that it immediately follows "and he's been telling me about this restaurant." Otherwise, it looks like the restaurant had "more stars than all the generals in "Dr. Strangelove" for that period of time.
Spell 'equals' instead of using '=' in paragraph six, the third sentence.
Your narrator very accurately, in the case of the knife, relays recently obtained culinary knowledge, but doesn't use any of the car jargon that supposedly confuses Larry. It would be more believable if she gets the name of the knife incorrect and employs a car analogy somewhere.
I really like your story. I would like a link to the book. If you want someone to read it over, non-professionally (I have no credentials), I offer my services humbly. I proofread everything I read anyway. It's a compulsion of mine.
PM me, if interested.
