...and the thorns won.
I am pretty sure I felt worse about it than he did, though. At least until we got home and I insisted on washing his face and applying an antibiotic ointment. Then he was quite sad.
By the way, his face is not bruised or whatever it looks like in this photo. That is just dirt. The marks under his eye are little bloody puncture wounds, but he is not as beat up as he appears here. This is just how he looks after rolling in mud and splashing through muddy creeks, etc. He says it was a fine time.
