Copies

My family was abducted by aliens and replaced with identical copies.  No matter how one looked at them it was impossible for an outsider to tell any difference. But if you had lived with them your entire life like me it was pretty obvious. For example, my little brother’s birthmark had switched places on his buttocks – which after all was impossible to prove. And my mom, her left cheek’s freckles had swapped location with those of her right. Myself, I was entirely the same, at least physically speaking.  But my soul and thoughts were exchanged for I don’t know what.
