simply due to the fact that she is an "s" and hopefully owned by a strict Master makes her guilty and she needs regularly hard punishments to bring her back into her reality, so she never forgets, what her daily duties are during her entire life: to serve her Master and this in all aspects of life and to have no other thoughts in her mind and soul than to serve and to love her Master and his way he does taking care of her... if his actions towards her is giving pain or joy, this does not count, she has to love everything and to be thankful to her owner and Master with all her heart!
