When I was little, I had a dog who loved when you pet him. However, when you stopped, he had a very unique way of getting your attention. He’d get as close to your arm as he could and then he’d rip out your arm hairs with his teeth. I’d like to think that if he had thumbs, he’d be a little more like this monkey here who has an itch on his head and does not want the girl from the video to stop scratching.
I’m not sure if it is wild monkey or if this is at a zoo. If it is wild, she’s lucky he didn’t just rip off her arm and scratch himself with it.
