Bang

"....and open flames and gas aren't a bad combination." You say, desperately explaining.
"What if I just turn the gas off?"
"There's already gas in the room. I can smell it. It smells like rotten eggs."
"Are you sure it isn't just the eggs from the fridge gone bad?" Your dad interjects, trying to be funny.
"Yes, I'm sure. Now either turn the gas off or get out of here..."
"The gas switch won't turn off!" You're mum says, panicing.
"Then, I suggest we get out of here."

Your mum and dad get up from where they are and quickly exit the room, and then the house with you close behind them. On the way out, you realise that your brother is still in his room, asleep.
