i have an identical twin sister so all the time.
but aparently theres a girl in Derby that looks just like me, so lots of my friends once started shouting silly things at her thinking she was me. wish i'd seen their faces when she said they were pissing her off!xD

plus at work people say things like "hows tha family" and i've never seen the person in my life O_O <----hahahahaha jojo
