I love fake flowers because (a) they are of a much higher quality than they once were and (b) I'm a hayfever sufferer! Thinking about this made me wonder about what quirky likes and dislikes your characters have. I'm thinking of those things that would really make them stand out to a reader. It is vital readers can tell characters apart and distinctive personality traits, likes and dislikes are great ways to achieve those necessary differences. We're not all clones after all, so our characters mustn't be either.
Think about also why your characters have their likes and dislikes. (Yes, people can and do have irrational likes and dislikes but, in fiction, you have got to convince the reader your characters are believable. I find having a good reason for them to be the way they are, which would include their tastes, is a surefire way of achieving believability).
