I’ve been walking a lot more since “quarantine”, partly because dog parks are closed, I need to exercise, and get out of the house. On one of my recent walks, I had a small pebble in my shoe. It was only slightly uncomfortable so I didn’t bother with it.

Not surprisingly, I got a blister and have been dealing with the annoyance for the past week.

It’s a decent metaphor about endurance, grit, decision-making consequences, and taking quick action.
