So you think you can parkour...

Younger Son (fascinated with the manly sport of parkour), was horsing around the library grounds leaping over picnic tables and jumping off retaining walls. After hurtling a railing, he stumbled in his attempt to avoid some plants in the landscaping, and he wedged a sliver of mulch into the palm of his hand.

He was discussing the experience with his brother who could not understand what had happened.

So, I explained:
"Younger Son injured his hand on a flower bed."

Heh.

A flower bed.
How manly.
