I’ve never told anyone about this. Do you think that in this world there’s only one kind of humanoid living being—humans and gorillas?

Actually, that’s not true!!!
When I was in my teens, I went up the mountain to chop firewood. Deep in the mountain wilderness, almost nobody ever went there. When I came down the mountain in the afternoon, I saw a humanoid creature not far away—except its front had long hair, and its back had short hair. It had four legs and two arms: its two hands and two feet in the front were on the ground, and its two feet in the back were on the ground. Its waist was connected to itself, and it made strange sounds. That was a conjoined person!
It scared me so badly that I hurried down the mountain, and for all these years I haven’t dared to tell anyone.
