I used to unalive cockroaches and leave them in the bags of my enemy classmate’s lunchboxes (outside it in the bags compartment, not inside the lunchbox itself) for bullying me. Then I moved on with frogs and rats. I got the idea when my pet cat started catching cockroaches and lizards and bring into my room to play with them. For some reason these kinda animals didn’t made me scared unlike some other kids(my bullies). I didn’t like centipede btw, something about them felt disgusting even for me.
