We had a kid that lived in the trailer park once. He was little probably like five or six. He thought he was a dog. He would crawl around everywhere he went. Bark, howl and growl. Refused to drink unless it was from a bowl on the floor.Back in our day we just called those kind of folks bonkers. Or bat scat crazy.
Interesting little fellow that crawled the crawl and barked the bark. He could teach some of these kids what legit means.
