Going overboard getting rid of junk

I'm at N's house with all the junk. I have a little camp place outside, a tent which is shared with lots of other people. I have made my bed, nice and comfortable. I get up and go outside and meet a
family who have just arrived. I think they are family friends of my parents. They have 6 boys. The youngest of them is very annoying. He has developed the habit of fighting for his place in the family by being stubborn and irritating, and manipulative, because he doesn't have the strength of the others.

As soon as they get out of the car he runs over to my bed and claims it as his own, saying that its his and he's been there for ages.

I run over to rescue it from him telling him its my space. He fights with me and bickers, at which point I think there's no point in fighting back; there's plenty of other beds out here so I decide to
choose my own bed elsewhere in the tent.

I come to a bed that is even nicer that my other one, at which point the irritating kid comes over and starts trying to pull the duvet off me, claiming that this is his bed. I tell him to stop being so annoying and to give back the duvet but he refuses.

At this point I get angry with him and smack him on the back of the hand, which makes him drop the duvet. He bursts into tears, but I know they are fake tears, because they only last a few seconds. I tell him that ill smack him harder next time if he doesn't stop.

I have a little fire burning amidst all the junk. I feel so hampered with all this stuff that I want rid of. I decide to chuck stuff on the fire, and I find some liquid in a bottle. Perhaps its flammable, I wonder... I chuck some on, and it flares up. I begin pouring this liquid around casually, amidst all the stuff, thinking this is the quickest way to deal with it all, but go alittle overboard, at which point I have to run from the flames, spilling the liquid as I go. It gets on my trousers and they catch fire. Soon I imagine I will here an explosion when some of this junk (old cars and such like) explodes...
Its a careless way to deal with it all...
