Back in 7th grade, we had a class called Lifeline. It was taught by our guidance counselor. We had the "warm fuzzies" and "cold pricklies" but we didn't have any visuals. The class was basically about self esteem and conflict resolution. Each week the counselor chose one person in the class to receive warm fuzzies from everyone else. We had to write on little slips of paper a warm fuzzie, and the chosen person could read the collected slips at his/her leisure. My most memorable warm fuzzie was from an egghead in the class who wrote, "To a girl who doesn't like flies' eyes."
The class ended up being a failed experiment which ended with us. I didn't know the concepts originated from a book.
