Scream-a collection of extremely short horror stories

Oh, sister

Your father comes in to your bedroom one night to tell you that he is taking your little sister out to get clothes. You don't pay much attention, until about thirty seconds later your Dad texts you telling you that he will be home from work soon. Frantically, you look outside to see If your " father" and little sister are still there, but all you see is the man that took her smiling at you from your car window, mouthing " Your next."
