Why Does my sister think I'm copying her?

Question

My sister is trying to be japanese and she finds anything japanese(even boys). She brought up Hello Kitty and when we were little we always loved it. Now, she says " Omg. You're such a copy cat." And she keeps calling me it because she said she loves it more and I'm a little b*tch. But we liked it at the same time and she still has a nerve to say I am a copy cat.

Q1. How do I make it stop?

Q2. Am I a copycat?

Answer 1

No, you're not a copy cat. Sometimes people just happen to like the same thing. My older sister used to do the same thing to me. Can't really do anything except ignore her (i.e. absolutely no response when she starts harping on about Hello Kitty). Hope things work out but in the meantime just tough these years out.
