HELP!!!Question about "INTROJECTION"

Hey everyone, I am a nursing student and we are doing our Psychiatric Rotation this semester. I have to do a skit in class friday and my topic is Introjection. My text book says that Introjection is when a person takes on the beliefs, attitudes or morals of another person as his own. I am really having a hard time coming up with a scenerio to portray in front of my class. Any assistance would be greatly appreciated.
Thanks in advance
Tammy
