The Ultimate "I Win" in a sibling fight

So I've always been arguing with my sister a little bit. I'm a bit more responsible now... but I still argue with her once in a while. And I got a driving suspension for my speeding ticket, but now I'm thinking. If anything she does really pisses me off. "No. I won't drive you." "Oh... you'll have to wait at Walsh for two more hours while I hang with my friends without you." I smell... at least some victory in the air. And injustice I'm sure in my favor, and I'll usually be nice, but once in a while, I'll get mad at her and maker her suffer a little more than I should, but that's ok. She only has one more year with me :)
