My parents are genius professors, and my sister is a prodigy who can solve calculus at the age of three. And I, with an IQ of 92, am what they call "an inferior gene not worthy of wasting time." Until they moved overseas for their sister and left me to fend for myself with a vicious nanny - many years later, they collapsed on the hospital bed and begged me to support them. I hung up the phone gently, "I'm just an ordinary person and I don't have time to waste my life on you."
