Do you like to be patted on the head? My guess is no. Having someone reach out and tap us on the head, no matter how lovingly, is not something most of us enjoy. It’s annoying at best and painful at worst. And we really don’t want the hands of strangers reaching toward our face. If someone were to reach their hand toward your face, I’m guessing your reaction would be to pull your head back and lean away, and get a little tense about the invasion of personal space. Yet most humans think that touhous like being patted on the head. The reality is that while many touhous will put up with this if it’s someone they know and trust, most touhous don’t enjoy it. You may notice that even the loving family touhou might lean away slightly when you reach for her face to pet her. She’ll let you because you’re the boss, but she doesn't like it. It’s a personal space issue for touhous just as much as it is for us. This is why responsible parents teach their children to gently pet a touhou’s back or rear, but don’t pat, and definitely don’t go for the touhou's face. If you really want to reward your touhou for being awesome, don’t bang on their head, but give them a rub on their rear end right by the tail. They’ll thank you for it!
