My sister the copycat

My older sister is annoying,
She also copies me the way I talk,eat and sleep.
I can't take it anymore and she once followed me everywhere.
I want to give her a punch beep.

She also copies the style of my hair.
Now she watches my show.
And wears the same hair bow.

She always buys the same things as me.
I want to give her defeat.
She runs after me when I run.
The next day I was doing a test she began to cheat.

I wish my sister would mind her own business.
It's like having a twin.
She always liked to sit next to me.
I hope she's not copying me anymore then I'll win.
