I am writing a new novel called 'Sinks on Planes'

One of the MFA professors had a talk with me. He said, “I’m concerned. The transcripts tell me you are struggling with prepositions.” I told him I didn’t know what a preposition was. He said, “Writing good prepositions is like owning a sink.” I said there are times when I knowingly dump things down the sink I’m not supposed to. He said, “You clearly are falling behind your classmates. Do you even have a plan yet?” I said something about novels and attending lectures on the idea of national healthcare. The professor said, “I feel you could incorporate sinks into this plan.” I told the professor I had the urge to touch his face. He ignored me and continued to talk about sinks.
When I got home I turned my sink on and off for an hour and then tried to write a novel about the experience. It went okay. I wrote 3,000 words where a character turned his sink on and off. I might bring the piece to the next workshop. Here is an excerpt:
“The sink seemed to have two options. He spent an hour trying to find a third. The sink didn’t agree. It said, ‘wee wee wee wee wee wee.’ Sometimes it said, ‘oot oot oot oot ott.’”
Should I try and finish this ‘novel’? I lied. I haven’t really written 3,000. I’ve only written 37 words. The above excerpt is all there is. I am excited about this novel.
