I have two older brothers, one older sister, and one younger sister.
Both older brothers are really chill and I've never fought with them before.
Older sister just complains a lot, bosses people around, and hits older brothers but I never fought with her before because she just likes to take care of me and the younger one
Younger sister is annoying because she's bossy, think she's right with everything, and I fight with her all the time.
Overall, I prefer my brothers. Maybe the second oldest one though because the oldest one is really random and likes to do crazy stuff.
