OTFD is a very effective way to talk about problems. The goal behind this communication tool is to articulate feelings in a positive manner while focusing on a solution to the problem.
Something you observe with your senses that anyone else can observe.
Example: “I noticed you came home 20 minutes after your curfew last night.”
A thought or opinion about what you observed.
Example: “My thought is that you did not care to keep our agreement”.
A feeling you had about what you observed.
Example: “I feel disappointed that you did not uphold your side of our agreement”
What you want (your desire).
Example: “My desire is for you to be responsible enough to get yourself home on time. If you are going to be late, I would like to have an agreement that you will call before your curfew.”
