I Have a Big Family

When I was 5, my mom broke up with my dad. They were never married. They were together for 15 years. When I was 9 she met my step dad. She married him 5 years later. I have 5 biological siblings (3 older brothers and 2 younger sisters) and 5 step siblings (3 step brothers and 2 step sisters). My step siblings are younger than me.
