ka-tet
A group of people forced to team up by destiny, like a bunch of kids who got stuck in a locker together and had to escape or die.
My ka-tet is my math teacher and his weird obsession with triangles.
My ka-tet is my friends who all got stuck in a zombie apocalypse.
My ka-tet is my mom and her crazy habit of talking to the mailman like he's a friend.
