I cut my arm.
It wasn't intentional.
I was walking up the hill from my trip to 7-11, and then I tripped.
I didn't fall, but I lost my balance and hit somewhere, and something scratched me.
That's how I got my cut.
Its not that big, but its deep.
I don't think it was a screw, since there was no rust on my arm, and all the screws around me at that point of time were seemingly safe.
But its hurts.
A lot.
And it just so happened to be my left shoulder again.
How wonderful.
