My XYY Brother, The Monster Inside

Summary

1

My mom was pregnant with my little brother, Liam. During a checkup, they discovered he had XYY syndrome. Everyone told Mom she should terminate the pregnancy. She refused, crying her eyes out. I asked her what XYY meant. She told me it meant Liam would be "extra strong, a real man's man," and that he'd protect me. I sort of understood, until Liam was seven and started bashing my mom's head in with a brick. Then I think I really understood what she meant.

I was six when Mom got pregnant.
