Well there are a lot of things that scare me, that's for sure, but what stands at the top of that list is my fear of being burned.
I'm a girl so my looks matter to me alot, the thought of possibly being in an accident where a significant portion of my body is burnt or disfigured and I actually live to tell the tale scares the living shit out of me. I honestly don't know what I'd do if all I had was my brain and not my beauty. I know it sounds quite vain and narcissistic but like I said, I'm a woman and my looks really do matter a lot.
I had a friend who got badly burned when some idiots poured fuel on him on his birthday just to scare him, then another one decided to bring a lighter close to him thinking nothing would happen, but they ended up setting him ablaze. He spend 4 months in the hospital recovering and till today the scars are still glaring on his body. Worst of all is that he was an aspiring male model, and a good one at that and his career just went down the drain. He made a full recovery but part of his right ear is a bit deformed now and what was once a handsome lad is now a shadow of himself.
The thought of the same thing happening to me or maybe even worse scares me more than I can even begin to explain on musing. Till date if I enter a kitchen and I perceive even just a little gas, I'll be out of there faster than you can even say fast.
There's nothing that scares me more than this, I think I'd rather die if I get burned like that. Living a life with a disfigured face or body just isn't something that I can do.
