Nature's Best

Walking to shul yesterday, Chana (6) says out of nowhere:

Chana: Dad, why do we have to kill the snails? It's not nice. They're part of nature.

Me: Huh? Oh, well, the snails are trying to eat our plants. They're part of nature, too. I'm just trying to protect the plants.

Chana: And I'm just trying to protect the bugs.
