Stubbed Toes

I suppose in a perfect world the sidewalks would all be smooth. They, of course, are anything but. Cracked, uneven surfaces warped by aggressive tree roots and neglect. I trip regularly, and, more disconcertingly, look around embarrassed that I did not see and avoid what is now so obvious.
What befuddles me about my embarrassment is, who was I concerned might see me and what am I worried that they might be thinking? My goodness. Who doesn't occasionally get tripped up or surprised by some protruding lip in the concrete? Is avoiding these imaginary humiliations worth walking with my head down, with eyes only for circumventing the next flaw in the path?
I think not. Count on observing a lot more stubbed toes in my stride.
