My Evil Twin

My evil twin is always mean,
I don't know what to do.
She drags me down and tells me off,
but my evil twin? Who?
She's not the kind to steal your clothes
and use all your shampoo.
We don't hug, have fun and make up
like normal twins would do.
She's rude and vile, not to anyone,
anyone but me.
She's always with me but
all the people I know would say 'whos she?'.
Its something I need to work on
but its time that I wake up and see,
my evil twin is not someone else,
my evil twin is me.
