I would say either Fictional vs. Non- Fictional or dogs vs. cats. Dogs vs. cats is the easiest for me because dogs like to play but they drool. Dogs can hurt people a lot but they are a companion. Cats on the other hand slunk back like lazy people.They don't hurt people much but they are sometimes annoying by going on your lap while you are doing something important. Dogs don't do that. So dogs=better ans cats=?!?!?! There we go!
