Siblings are weird. That's not an opinion, this statement is a fact.
And it's not just with siblings, just now my cousin and I got into an anime-style-over-the-top fight, with air punches, kicks, and terrible half assed karate chops. This lasted about twenty seconds, then we went on like it never happened.
Then right after, I got into a dance party with my sister that lasted a minute.
I think we both got a boost of serotonin after that.
