You haven't learned life's lesson very well if you haven't noticed that you can give the tone or color, or decide the reaction you want of people in advance. It's unbelievably simple. If you want them to take an interest in you, take an interest in them first. If you want to make them nervous, become nervous yourself...It's as simple as that.
People will treat you as you treat them. It's no secret. Look about you. You can prove it with the next person you meet.
I read Churchill's statement years ago and discovered, upon testing the challenge, the truth of his observations.
"People will treat you as you treat them."
The novice teacher who struggles to develop productive relationships in a classroom would do well to take Mr. Churchill's advice. If you want respect, give respect. If you want students to be interested in what you have to say, be interested in what they are saying. If you act like you can't stand being around them, they will hate being with you. If you treat them like morons, they will act moronic.
Like the man says, "It's as simple as that."
