1. Do not listen when having a conversation, and when recalling it later, be sure to include facts which were never mentioned. For those brief periods you were listening, do not use logic in your interpretation of what was said.
2. Create a far fetched story and accuse the person of lying when they don't admit to what you say they "did" despite the fact they have never lied to you before.
3. Never allow facts to get in the way of your emotions.
