Huh?
At some point today, probably at work I gashed open my arm. Ok, maybe not gashed, but its a good size cut with a fair amount of blood. However, I have no idea when or how. There is no damage on the sleeve of the jacket I have been wearing all day. Nor did the blood reach my hand. I get home and take my acket off and there is blood all over my arm and the inside of my sleeve. WTF?
