A sister is someone who will be your
friend at some point, and be your biggest enemy the next point. She can take you to
Micheal's in the morning, and lie to you the next. She may also blackmail you when you skip school, even though you spent the day with her. Also she will not buy you a Christmas present, or a birthday present; but she will buy a
guy (that'st not her boyfriend) Ugg moccasins.
