I stacked my bike this morning

That's right, a crash. Riding along the same path I always ride on with a highly experienced rider next to me on my right, he decides he wants to turn left with no indication whatsoever. He bumps me hard and I end up climbing - then crashing - over an island in the middle of the road and take some bark off my knuckles and shin, he hits the deck hard on his left shoulder. He thought it may have been dislocated, but rode off anyway.

It's just one of those random things that happen in life.
