You've got to be kidding! Do you know what I've put up with from you?...Goodbye Andy.
I thought you cared!
No! I swear I didn't mean to! It was an accident! A horrible, horrible accident!...No! No! No! I'm sorry Rob...
Not bad. I'm dealing with the situation...No bad dreams, honest.
Well Andy, it's been a few weeks since we've talked. How've you been? No bad dreams?
This shows an external conflict, because here Andy and Keisha were arguing at the talent show on whether or not Keisha actually does care about Andy or his feelings. Keisha tried arguing back at him to prove she does care, but she just couldn't stand him anymore and left without singing the song she was dedicating to him.
This is an external conflict, because Andy is having problems with dealing with someone else. Rob. He has a dream about Rob, and in his dream, Rob is telling Andy to join him, and Andy keeps telling Rob to leave him alone. He keeps saying he's sorry and that he didn't mean to hurt him. Andy is shaken up by this, because Rob even said his death was all Andy's fault.
This is an internal conflict, because Andy has made the decision to lie to Dr. Carrothers about him "dealing with the situation", and how he has, "no bad dreams". Andy is really depressed and is constantly thinking about Rob. He also just recently had a dream about Rob and he's not telling the truth. This causes people, including Dr. Carrothers to believe he is getting better, when really, he is not.
