Conversation with a school child.

Last year one of my children had a conversation with Clara who lives in our neighbourhood.
Clara and her brother Mike were trampling mushrooms to pieces, which my children didn't like, so my oldest went up to them and asked them to stop wrecking nature for no good reason.
The Clara stated that it was important to trample mushrooms because mushrooms are a hazard to nature.
My child replies: "Mushrooms are nature you dope, the crisp bag and plastic bottle you just threw down are a hazard to nature." and left it at that.
