"So what are you planning to dress up as? I'm going to go as a witch!"
"What? I'm planning to dress up as a witch too! I already made the props and a big part of my costume!"
"What?! Dang it! I've already made the costume and props too! What are we supposed to do now?"
"Hmm... Rock, paper, scissors to see who has to back down and choose another costume?"
"Uhm, I don't think that's a good idea. Rock, paper, scissors is a little unfair, don't you think? One, it's a game of sheer luck and it won't be a fair duel. If you got luckier than me, than I have to pick something else be and I have to make a whole new set of costume and props!"
"Heh! Are you scared that you'll lose? That you'll be the one who had to give up the witch theme?"
