Apparently, when you write a novel, you have roughly...well, let's see...10 trillion things to think about. One of those things is whether or not anyone on the planet likes your protaganist.
But sometimes, and this has to be quite skillfully done, nobody has to like your protaganist. He or she can kick puppies, stop funding for AIDs research, laugh at dying children...the works. You just have to make your readers empathize with them in some way. Empathy man. That's the 9,999,999,999 thing you have to think about.
So, in an effort, NOT to think about it, I wonder... who is your favorite character to hate?
For some reason, the first person to come to my mind is Brenda Walsh from 90210.
