What is the underlying message when someone says, "You cause me to become impatient," or, "This makes me impatient?" The assumption here is that another person or a specific situation is the cause of your impatience.

Actually, impatience is a choice. It is one reaction out of many that can be chosen. If you blame your impatience on an external factor, you are to some degree giving up on your own power to create your reaction. Your reaction in any situation always depends on how you personally and subjectively evaluate and perceive that situation.
