My sister is very different from me. She is almost 12 years younger than me, but the personality differences are obvious; my mom got remarried and really wanted another kid so she could have something to baby. My mom babied the hell out of her, and it shows. She is a girly girl, wannabe hipster, very emotional, very dependent on others, and not very nerdy -- none of which describes me, even at her age. She's also much more outgoing and social than I am. About the only thing we have in common is our sense of humor and the occasional similar taste in movies/TV shows (she watches Doctor Who... but then ruins it by watching everything on the CW). She also doesn't read, whereas I lived in books at her age.
