Lying includes not simply saying untruths but also exaggeration, communicating mixed messages, and implying things you do not mean. Lying includes nonverbal communication — acting one way when you feel another. It includes the unwillingness to communicate — shutting yourself off. You are lying to another by withholding the truth of who you are.
When we minimize, dismiss, deny, and pretend something isn't happening we are also engaged in lying. Often we lie to ourselves.— Brenda Shoshanna, The Anger Diet
