Butterfly Stops at Eighteen

When I was a kid, every time I did something wrong, my dad would force me to trample to death a silkworm I raised. I cried and picked one from the pile of silkworms. I remembered that the blood of silkworms was green. My mother laughed on the side, "Your daughter is so stupid, she picked the fattest one and trampled it to death." Later, when the silkworms were not enough, I jumped off the building and killed myself. My blood is red. I woke up and found that I was back when my mother was pregnant with me. I looked at her belly. This time, I'm going to kill myself early.
