People follow patterns. That's what people do. You are a person. You follow patterns. I am a person. I follow patterns. What is the pattern? Everybody follows their own patterns. Sometimes, it can be upsetting when somebody else's pattern does not match with your pattern. Your pattern might not make sense to me. This may cause an emotional reaction in me. I may get angry. I may get upset. I may try to make your pattern match my pattern. I may get sad. I might not care. Your pattern might make me happy. If you change your pattern, that might make me sad. Why would that make me sad? I will be sad because I included your pattern in my pattern of how your pattern is supposed to go. The pattern that made me happy was my pattern of you. But my pattern of you was wrong. Being wrong does not fit in many peoples patterns.
