Discussion: What turns you off?

I can handle almost anything with literature. I don’t think I’ve found a level of swearing that bothers me. I don’t mind graphic details. In fact, I tend to embrace them. Give me the all the cursing, the blood, guts, sex, and… well, pretty much anything you want to throw my way. I don’t care. Doesn’t bug me. 
Just don’t give me boats. Please. 
I firmly believe that everyone has something that turns them off in literature. My turn off point is boats. I’m not sure why, but if a book has a plot that mostly takes place on a ship, I just can’t find it in me to care that much. It could be the best written book on the face of the planet with the most awesomely developed characters in the history of literature, but if it takes place on a boat, I just turn off. 
Maybe it’s because the only boat I’ve ever been on is a ferry taking me somewhere across the Puget Sound so I can’t really relate or picture anything nautical and I usually don’t care enough to figure it out. Maybe it’s because the world just seems too small to me if it’s mostly boat-contained. Perhaps I have just spent too much time landlocked. I’m not sure, but whatever it is,  I haven’t ever found it within myself to fully get over it. 
It doesn’t really make sense. I spent roughly nine years of my life as a competitive swimmer. If there’s one thing I understand and embrace, it’s water. I just don’t care about boats, or books filled with boats. No matter how hard I try, they just turn me off. 
So, what turns you off? 


P.S. I’m going to try to post these discussions every Sunday. Yes, I’m posting it 30 minutes shy of Sunday this week, but I don’t care.
