Crashed my bike last night.

Those are friction burns- I was wearing a tough jacket and it didn't tear.
There are two of them because I rolled once- crashed, rubbed my elbow, rolled over, and rubbed my elbow again.

This is pretty much the extent of my injuries, save for a scraped knee and a hole in my right hand, which is fortunate because I wasn't wearing a helmet. A lifetime of martial arts has taught me how to roll and protect my head, although I clearly need to work on where I put my elbows.
