<human>: This happened two or three summers ago when one of my sisters and I were home alone at around eleven in the afternoon. 

So my parents and our other sister were out and they decided to leave two very irresponsible teenagers alone in the house. I was extremely hungry so I decided to go make some toast in the toaster oven in the kitchen. (The toaster is pushed up against the wall right next to the glass sliding door and we keep the curtains pinned to the table that it sits on). 

My sister was in the dining room and when the toast was done I, being the lazy bum that I am, decided that no, I don't need a plate, I can just use this random piece of parchment paper sitting on the counter. 

The bread and toaster were still hot so I kinda put a little bit of the paper in the toaster and started teasing the bread out. It was hot so I was being careful and me being careful = my hand shaking like crazy. So my hand was shaking and the parchment paper kinda brushed up against the inside wall of the toaster. 

Then it bursts into fucking flames. 

So now my sister leaps out of her chair and starts panicking and I'm an idiot so I'm just staring at this piece of burning paper in my hand and what used to be a decently sized piece of parchment paper was now about an inch from my fingers. 

This is when my sister really started panicking because I was standing right next to the very flammable curtains and she starts screaming "WATER!" and I was still standing there mesmerized by the fucking flame in my hand and then she gave me a shove. That's when I snapped out of it and threw the fire in the kitchen sink, but not before it basically engulfed my entire fucking forearm and burned my hand, also leaving a good black mark on the curtains.

Can you summarize the given text in a few sentences?
<bot>: I was hungry and decided to make toast, and instead of using a plate like a normal human being I grabbed a piece of parchment paper that magically burst into flames and burned my arm hand and curtains
