Scars:
I have about 50 or so totally random scars all over my body from diving into things (trees, dumpsters, steel fences, bushes, ect...) after having a dozen or so too many drinks.
I've one on my right arm from throwing a fit and stabbing myself with an exacto knife in highschool. I was protesting another students choice in music that day. Don't play Phish anywhere near me!
I've a few scars on my right hand from punching a window. I was drunk, naturally.
I have a few barely visible scars above my lip from being attacked by a dog as an infant.
That's all I have.
As for fear of the future, fuck it. Whatever happens, happens.
