I remember of my childhood that me and my friends used to kill big insects when we found one. Also we killed a lot of those red slugs that came up after long rains and tadpoles in the river. Sometimes we killed fireflies, but usually didn't.
Kids can be very macabre; when we found dead birds fallen from a tree we acted a funeral and build a little grave. Ah, and we did races with little frogs, but we killed them only accidentally.
Have you too been so cruel with little creatures? And why kids do such things?
