I'm really annoyed .. Why does she do this??

My friend copies me everything I do! And it's annoying 😩. It's like I can't live. I did this really unique hairstyle messing around with my hair and shit and next thing you know she's copying me 😐😐😐😐😐. Some people say "you should be happy, that she's copying you" but no I'm not. I don't like that and I never will
