Does your sister or brother provoke you, or do you provoke them?

Provoking might as well be a family tradition between siblings. My older brother used to provoke me, I provoke my little brother... My little brother provokes my other little brother. It's a cycle. I think it is a dominance trait. Provoking your older or younger sibling is a way of dominating over them, or just for entertainment. My older brother would take my things, or jab/push/hit me to get me to react. He found it 'entertaining'. I provoke my little brother in alot of the same ways. I don't know why it happens, it just does.
