Whether humans or small animals, the head is a sensitive location, so it is not easy for people to touch it if they are not highly trusted. And sometimes even the other side is the most familiar person because you hate it. What would you do if you didn't want to be hit on your head?
There's a guy who's got a dog in his family, and he doesn't like to be rubbing his head, even if he's the owner. On this day, for example, the Internet just reached out, and the dog was a little careful, and when the master's hand was too close to the top, it would lift its head up, and when the hand was coming close to its head, the dog would basically look up to the limit! In order better not to allow the master to touch his head, it's starting to play a circus!
Seeing how stubborn it is, it's better not to let others touch it. But it doesn't run away, it just stands still, it shows or wants to believe in you, it's only the head that can't touch it!
