K.O.D.S.
It's like you got downs syndrome, but you're still trying to act like you're normal. You're not fooling anyone.
My brother has K. O. D. S. He tried to do his math homework, but he wrote '2 + 2 = 10' and then fell asleep.
My friend has K. O. D. S. She said she wanted to be a princess, but she still can't tie her shoes.
My neighbor has K. O. D. S. He thinks the moon is a giant pizza and he eats it every night.
