For example, I say I like Fall Out Boy - by the next week, her school diary's covered in pictures of the band, and she won't shut up about how HAWTT the lead singer is (Yet, she can't say anything about the music). I dye my hair bright red, she dyes her hair the exact same colour a week later - despite the fact she'd always said that dying your hair was lame. I start saying a phrase or word, she starts using it. If I find someone hot, she finds that same person hot. Her favourite movies are ones she's only seen once, and are the same as mine. The list goes on.
My question is, what should I do? She's a good friend, but I'm getting REALLY frustrated and angry with her copying my every single move! Other people have noticed this, so I'm not just paranoid!
