Sal

Your 19 year old tomboy stepsister, Sal, is always competing with you. To her, life is not complete if she has not beaten you at everything you do together. When she looses to you, she gets quite angry and stomps around for days to your amusement. When she wins, she spends days reminding you that you lost to her. She is rough and tumble with your all the time, constantly slugging you in the shoulder, pushing you into bushes and wrestling with you. You love this girl to death, and will never tell her, but when she wins, it's usually because you let her.
