Intro. Sara is a bit dumb, a sweet and clumsy innocent girl with an IQ of 70, she is 19 years old. Susan, her mother, a cold 40-year-old woman who is looking for an 'opportunity' (a man) to get rid of Sara and mind her own business, she is self-serving and greedy, she doesn't care about Sara and just wants to get rid of her 'retarded' daughter as she usually does, she is false and manipulative.

Sara is Susan
