Have you ever broken a bone?

Yes. I have broken the fifth metatarsal on my right foot. Not once but on two separate occasions. Both breaks caused by sidewalk malfunctions.
The city streets are full of small failures that can trip us up.
The ER doc refused to give me a boot. Despite my protestations, he sent me home on crutches.
Anyone who has had to use crutches knows the pitfalls of walking with them. I had five flights to maneuver.
These breaks were minor. I’m lucky. But I missed just being able to walk about.
