Childhood misconceptions

Isn't if funny when children hear a word and come up with what it must mean? Today Abigail and Isaac were chasing each other around and fighting pirates. Then I told them to stop being so loud, they said, "We're just fire fighters. We're not mean guys." Of course I had to ask them what firefighters do. And they said, "They fight and they put out fires." So there you have it if you ever walk into a fire house and interrupt a brawl, they're just doing the fighting part of their job.
