<human>: Give me the gist of the text in a nutshell

This goes back to time when I was may be 6 - Curious and inquisitive; like most kids.    
So I noticed that fire is fun. Which took me to experiment many things. Burning paper, wood, candle, fireworks, thread and observe the flame, putting salt on fire and see the color change ... like that. I was on the roll.     
One fine afternoon when most of family members were taking afternoon nap, an inner voice asked me to move. And I took a paper, went where my granny's old iron sheet cupboard was. Lit the piece of paper and pushed it underneath. After few seconds the paper burnt and show was over.    
I was wrong. After maybe 30 minutes, smoke was observed in the house. And another 30 min of search, starting from the obvious kitchen, revealed that it is coming from the cupboard.    
And when my poor granny opened that cupboard, got the shock of her life. She found that all cloths were burning inside.    
No one could understand why and how the hell that happened. Except me. And this great family secret was kept for years till one day when I revealed it during a family event. And now I'm famous.
