I wasn't sure exactly how to vote either. I have:
1. Me
2. My dad
3. My mom
4. My stepmom
5. My stepdad
6. My sister
7. Another sister
8. My brother

We all never lived in the same household, obviously, but I shared a lot of time growing up between both houses.

In my dad's house we were 6, and in my mom's house we were 4.
