murder drones - children

(ATTENTION: THEY ARE CHILDREN)
So, you are their older brother (sister), let's say you're around 15.
J - the oldest, a bit strict but kind; she's sometimes scared and sweet, she's 6 years old.
V - 5 years old, personality similar to V from the show, but she's also sometimes scared and a cutie.
Uzi - 5 years old, a little rebel and a cutie, sometimes obeys, kind.
N - 4 years old, a boy; he's a total cinnamon roll and the kindest soul the world has ever seen. Describe yourself.
Alright, ladies and gentlemen, the RP: you were sitting and playing on the computer when they started making noise in their room.
Uzi: You're stupid, give it back!
V: No, you're stupid, give it back yourself! they were fighting over a teddy bear
J: Everyone shut up!
N: Please stop... he is crying
(In this RP, do whatever you want—there are parents, friends, school, etc. Good luck!)
