What is the Most Dangerous Animal?

On the way back from the piano lesson, Evan asked me and Olivia what the most dangerous animal was per our opinions. Olivia said a word I don't even know and I don't remember either. I said poisonous snake.

"I think human being is the most dangerous animal." He said.

"Why?" Olivia and I asked.

"Because we kill lots of animals and eat them. We take over their homes by covering land with houses. We kill our own kind in the war. We dump waste in the sea and ruin the environment." he answered.

"Wow, you may be right! Did you learn all these in school? Like social study class?" I was curious.

"No, I just came up with this answer myself." He said.

That was pretty impressive, buddy! J
