I think I'm pretty dedicated to good manners

So, I've realized that like any good Canadian should be, I am dedicated to being polite. I realized this when I woke up this morning. I had just finished having a dream that was strange. It was kind of funny and surreal.
It takes place in room of the third floor of a building. The room was small and empty with one large window. There were about 3 of us in the room. When I looked out the window, there was some people down on the ground below, supposedly waging war against us. So, in essence, the guy right below our window, down on the sidewalk was trying to kill us. (This dream is getting exciting now, isn't it?) Anyways, he had this contraption sitting between the 2 wheels of some sort of bike trailer. The contraption had a pipe that went straight up to right outside our window. Then there was this dinky little hose that attached to the top of the pipe and went inside our window. Anyways, this whole contraption was some sort of flame-thrower that the guy down on the street was controlling. He was shooting bursts of flames in through the window, trying to burn us up. The flames narrowly missed my friends standing on the left side of the window inside the room (I was on the right). Everyone was ok though.
I thought this wasn't cool that we might get burned, so I gave the pipe outside a shove so that it fell away from the building. This upset the guy outside a bit but he quickly got his flame-throwing contraption upright again and shot more flames inside our room.
This next time, in order to protect us, I yanked the hose off of the pipe. This caused the flames to shoot straight up into the air out of the pipe outside our window whenever the guy below pushed his button. This made the guy below really angry and he started yelling at us to give him back his hose so he could kill us with it. He even climbed up the pipe to the window to look in at us and demand the hose back. I told him I would give it back if he promised he would stop blowing flames in our window. I explained that he had almost burned my friends and that he wasn't being polite. He retorted that I wasn't being polite by stealing his hose. I couldn't argue with this, so I planned to throw the hose back to him while he hung on to the window sill (we were standing by the door of the room). I figured that I could then make a run for it along with my friends if I had to.
Before I had a chance to give him back the hose though, he told me that we were in a battle with each other and that I should started acting like it. Then he proceeded to throw a hammer at us. The hammer stuck into the door right beside us. This got me quite upset and I actually yelled at him: "How Rude! You could have put someone's eye out with that!" He resonded by saying, "I know! I'm trying to! This is a war! If you don't like it, you can leave!"
At this point, I yelled, "Fine!" and threw him back his hose and left.
As I walked away down the hallway, I was muttering to my friend about how rude the guy at the window was and that there was no excuse for such impoliteness. I don't care if it is a war, I still think it is pretty rude to try and kill someone.

Well, that was the dream. Get what you want out of that. I thought it was interesting that I seemed to not only get upset at the guy trying to kill us, but that I got even more upset at the guy's unwillingness to change his ways when I informed him about how rude he was being. Is there no respect for manners these days?
