Ever have a really nice teacher with weird vibes?

The ones that come up to you randomly and rub your back in a circular motion and ask you how you are. I had mine in elementary. They aren’t nice to everybody, just a couple kids at a time. I asked one of my friends and she said she shared a similar experience. Why are you constantly trying to comfort me mr. teacher I’m not even in any distress. Are you just being nice to me because I was well behaved?
