A childhood belief about general

When I was a kid, my mother used to tell me that if you opened the refridgerator door too long, your face was freeze in the same position for the rest of your life...She even backed the lie with the story of her distant aunt who had her face frozen and her lips stayed curled forever. So I made a serious effort to make my face a pretty as possible so it if it ever froze, I woud still look nice. I did try to avoid smiles however because I feared that I would have a smile on even if I was angry.
