Watch out, an enemy behind you. He has a knife! Shoots arrow! That was a close one I Dodged Get off of me! Why are you attacking me, when I kept the enemy from knifing you in the back? Are you mad? Oh no I'm just confused Me thinks you are mentally ill! I think you need to see the physician to be cleared of any illness, you baffoon! Well, I been stuck in the murder hole for a while now  Watch out he is still alive! This time kill him! Make sure he moves no more! Whew that was a close one archer Too close! I realize its hot here in this hole! I have spent many an hour in a hole and I know that it gets hot. Make sure you carry plenty of water to keep you from losing your mind! I want to escape I have nothing with me  I can share what water I have with you today! If you spend another day in here you will need to remember to bring it with you. Are you clear on that? Indeed , never will I return here
